Summary: The lattice volume of ice VIII was measured in different pressure-temperature pathways, and it was found that the volume depends on the pathway, suggesting that deviatoric stress results in a larger volume. Dense ice is in the ice VIII phase with a molar volume of 6.56 cm(3) and in a high-pressure phase with a molar volume of 6.45 cm(3) at 10 K. The pressure can be estimated as 57.0 & PLUSMN; 3.4 and 60.4 & PLUSMN; 3.6 GPa, respectively.

Summary: This study investigates the influence of nuclear quantum fluctuations on the properties of dense hydrogen, focusing on its potential metallization. Raman spectroscopy and synchrotron infrared absorption measurements are conducted on deuterium at 460 GPa and 80 K, revealing the isotopic effects on the electronic and vibrational properties in phase III. The findings also suggest a probable transition to metal deuterium, occurring at a shifted pressure compared to hydrogen, and are compared to advanced calculations quantifying the reduction of the band gap caused by nuclear quantum fluctuations.

Summary: Hypercrosslinked polymers HCP-DMF and HCP-DMF-SO3H, containing abundant and flexible DMF moieties, demonstrated excellent performance in converting NaN3 to benzylic azides and 1,2,3-triazoles in EtOH (95%) due to the solvation microenvironment provided by the pseudo-DMF moieties. This avoided the use of risky DMF and improved the separation processes of the products.

Summary: Silicate perovskite, the most abundant mineral in the Earth's lower mantle, exhibits different crystal structures under high pressures for FeMg0.5Si0.5O3 and Fe0.5Mg0.5Al0.5Si0.5O3 phases. FeMg0.5Si0.5O3 phase adopts a novel monoclinic double perovskite structure at pressures above 12 GPa, while Fe0.5Mg0.5Al0.5Si0.5O3 phase adopts an orthorhombic perovskite structure at pressures above 8 GPa. The FeMg0.5Si0.5O3 phase undergoes an iron spin transition at pressures higher than 40 GPa, while no spin transition is observed for the Fe0.5Mg0.5Al0.5Si0.5O3 phase.

Summary: RE2O2S:Eu3+-Ln(3+) (RE = La, Gd, Y, Lu; Ln = Pr, Tb) samples were prepared and studied as red persistent phosphors. Eu3+-singly doped RE2O2S showed weak TL glow peaks, but additional strong TL peaks were observed by codoping Pr3+ or Tb3+ ions. The PersL and TL spectra only showed luminescence from Eu3+, indicating that Eu3+ acts as a recombination center while Pr3+ and Tb3+ ions act as hole trap centers. La2O2S:Eu3+-Pr3+ was found to be the best composition, displaying strong red persistent luminescence at ambient temperature.

Summary: The study of host-guest chemistry in coordination cages is of great importance for applications such as drug delivery, sensing, and catalysis. This paper demonstrates the use of various techniques to investigate the host-guest chemistry of a novel Pd2L4 cage, which has high affinity for selectively binding dicyanoarene guests through hydrogen bonding and other weak interactions. Additionally, Raman spectroscopy is shown to be a valuable tool for analyzing coordination cages, using alkyne and nitrile reporter functional groups.

Summary: Phosphate ester bonds are stable in nature and can be isolated using a combination of phosphoryl and calix[4]arene moieties. In this study, hydrolyzed phosphoryl-calix[4]arene ligands were formed through Ln(III)-mediated P-OEt bond cleavage in L-PO. The resulting Ln(III) species were trapped as dimers, and the Dy derivative exhibited slow magnetization relaxation. This strategy can be further applied to create a broader range of hydrolyzed platforms that mimic nuclease enzymes.

Summary: A new family of 3d-4f complexes with an unusual four-blade propeller topology containing four Cu centers is designed using the multinucleating ligand H6L. The coordination of four {Cu(H4L)} units around the central Ln ion is achieved by using Cl- and ClO4- as co-ligands. Magneto-structural analysis reveals that the geometric arrangement of the Cu(ii) centers defined by the H4L2- ligands controls the magnetic communication between the different metal centers.

Summary: Reaction of Gd(OAc)3 center dot 4H2O, salicylaldehyde, and CH3ONa in MeCN/MeOH leads to the formation of [Gd12Na6(OAc)25(HCO2)5(CO3)6(H2O)12]center dot 9H2O.0.5MeCN (1 center dot 9H2O.0.5MeCN), which exhibits a quadruple-wheel structure composed of two {Na3} and two {Gd6} rings. The magnetic properties of 1 show weak antiferromagnetic interactions between GdIII ions, resulting in a record magnetocaloric effect at low magnetic fields and temperatures. The magnetic entropy change reaches -Delta Sm= 29.3 J kg-1 K-1 for full demagnetization from B = 1 T at T = 0.5 K.

Summary: The reaction of 2,2'-bis-p-Bu-t-calix[4]arene (H8L) with Cu(NO3) (2)center dot 3H(2)O and N-methyldiethanolamine (MedeaH(2)) in a basic dmf/MeOH mixture results in the formation of [Cu-II (16)(L)(2)(Me-dea)(4)(mu(4)-NO3)(2)(mu-OH)(4)(dmf)(3.5)(MeOH)(0.5)(H2O)(2)] (H6L)center dot 16dmf center dot 4H(2)O (4). The metallic skeleton of the compound consists of a tetracapped square prism, [Cu-12], with Cu-II ions housed in the calix[4]arene polyphenolic pockets. Magnetic measurements show antiferromagnetic exchange interactions and a ground state of S = 1, while EPR indicates a large zero-field splitting.

Summary: Ultrafast transient absorption spectra were recorded for [MnIII(cyclam)(H2O)(OTf)][OTf]2 in water to study the equatorial expansion restriction after dxy-dz2 electronic transition. Strong oscillations in the excited state absorption signal were attributed to an excited state wavepacket. The structural rigidity of the cyclam ligand causes a complex reaction coordinate with certain frequencies, leading to a shorter compressed-state lifetime. Complementary density functional theory quantum chemistry calculations support the successful restriction of the wavepacket motion.

Summary: Equimolar amounts of MnBr2 center dot 4H(2)O and HL1 react in a basic MeCN solution to produce [Mn-4(II)(L-1)(4)Br-4(H2O)(4)] (1), with a [Mn-4(II)] tetrahedral metallic skeleton and a [Mn-4(II)(mu(3)-O)(4)] cubane cluster core. Replacement of MnBr2 center dot 4H(2)O with Mn(O2CMe)(2)center dot 4H(2)O yields [(Mn2Mn12O2)-Mn-III-O-II(L-1)(4)(OAc)(22)] (2), which can be described as a series of edge-sharing [Mn-4] tetrahedra that form a linear array with a corkscrew-like twist in each [Mn-2] pair. Reaction of the triangle [(Mn3O)-O-III(OAc)(6)(py)(3)](ClO4) instead of a Mn-II salt results in [(Mn14Mn4O14)-Mn-III-O-I(L-1)(4)(HL1)(2)(OAc)(18)(H2O)(2)] (3), featuring three vertex-sharing [Mn-4(III)] butterflies flanked by a [Mn-4(III)] cubane and a [(Mn2Mn2II)-Mn-III] tetrahedron. Magnetic measurements of 1-3 indicate antiferromagnetic exchange interactions, with a diamagnetic ground state for [Mn-4] (1) and Single-Molecule Magnet (SMM) behavior with U-eff = 22 K for [Mn-18] (3).

However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
