Summary: This Review discusses the recent trends in key synthetic strategies for achieving exotic magnetic properties and provides representative seminal reports. Special emphasis is given to monomeric high-performance Dy(III)-SMMs realized through crystal field, predominant bond, and organometallic approaches, as well as stimulating reports on endometallofullerenes and radical-bridged systems with strong magnetic coupling. The role of spin-vibration coupling in magnetic relaxation is also highlighted. More demanding theoretical studies are anticipated to predict promising molecules with magnetization blocking at practical temperatures.

Summary: The treatment of CoCl2 center dot 6H(2)O and tris(pyrazolyl-1-yl)borate tricyanoiron(III) anions at an elevated temperature resulted in two less-common pearl-chain-like compounds. Compound 1 exhibited typical single-chain magnet behavior with an effective energy barrier of 28.0 K, while compound 2 did not show Glauber dynamics despite their similar structures. Changes in the local coordination environments of cobalt ions and cyanide linkages were identified as contributing factors to the significant difference in their magnetic properties.

Summary: Two isomeric Co(ii) complexes with the same molecular formula of [Co(napy)(2)(NO3)(2)] (napy = 1,8-naphthyridine) were synthesized and their structures were determined. The complexes exhibit highly irregular six-(1) and seven-coordinate (2) geometries. Magnetic measurements, X-band EPR data, and theoretical calculations were conducted to investigate their properties, revealing field-induced slow magnetic relaxation in both complexes, with 2 attributed to an easy-plane anisotropy.

Summary: In this study, two dysprosium(III) single-molecule magnets (SMMs) were prepared using a pseudoallyl ligand, N,N'-chelating amidinate (Am), and pentamethylcyclopentadienyl (Cp*). The obtained SMMs, [{(AmiPr)-DyCp*(mu-Cl)}2] and [AmdippDyCp*(Cl)(mu-Cl)Li(THF)3], exhibited distinct energy barriers (Ueff) of 97 and 472 K, respectively, with the latter value similar to a homoleptic Cp*-based Dy-SMM.

Summary: In this study, a light-induced substance conversion system using an Er(iii) coordination polymer and its Y(iii)-diluted analogue was reported. The transformed products exhibited higher T-XM values and lower effective energy barriers for magnetization reversal compared to the untransformed compounds. This work not only provides a new light-conversion system, but also reveals the nature of photo-induced variation of magnetic properties.

Summary: A new octahedral luminescent Single-Molecule Magnet (SMM) with massive crystal-field splitting and an anisotropic barrier of 1385 cm(-1) is reported, with a unique mechanism behind the high blocking barrier revealed through magnetic measurements and ab initio analysis. The novel mechanism involves quenching of one-phonon transitions between low-lying crystal-field multiplets, forcing relaxation to proceed through a fourth doublet. The short relaxation time observed is attributed to non-axial anisotropy and tunnelling relaxation path via interaction with nuclear spins.

Summary: This study systematically examines the origins of different abnormalities in the Raman exponents of single molecular magnetic relaxation, clarifying past misunderstandings and the appropriateness of fitting procedures. It is found that exponential laws raised by optical phonons can yield spurious power laws with low exponents, indicating long-standing misunderstandings of the origins of low Raman exponents. The presence of these exponents suggests the importance of the local dynamical environment for magnetic relaxation in this regime, resulting from spin-lattice coupling with optical modes.

Summary: Single-molecule magnets (SMMs) are molecules that exhibit slow relaxation of magnetization and have potential applications in information storage and quantum computing. To make them practical, high blocking temperature and effective energy for magnetization reversal are required. Enhancing magnetic anisotropy can reduce quantum tunneling of magnetization. Among transition metal ions, Co(II) is a superior choice for designing single-ion magnets.

Summary: This study reveals that the oxidation of Y-356 in E. coli ribonucleotide reductase is regulated by a specific residue, E-52, which facilitates proton transfer through a water channel at the subunit interface. The E(52)Q variant is unable to oxidize Y-356, indicating the essential role of E-52 in proton management.

Summary: Ribonucleotide reductases (RNRs) are pivotal in converting nucleotides in all organisms. The Escherichia coli class Ia RNR consists of two subunits, alpha and beta, forming an asymmetric alpha alpha 'beta beta ' complex. The reactions involve a proton-coupled electron transfer pathway, in which key residues E52[beta], R331[alpha], E326[alpha], and E326[alpha '] play a crucial role. Mutagenesis studies and photochemical assays provide further insights into the mechanism of proton transfer associated with Y356 oxidation.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.

Summary: This study presents the first direct spectroscopic evidence of a cyclic seven-membered iminoborane. Compared to linear amino-iminoboranes, this cyclic iminoborane exhibits weakened bond strength and lower Lewis acidity value. The study suggests that the reduced ring strain of cyclic iminoborane prevents nitrogen fixation but allows facile (2 + 2) cycloaddition reaction with C2H4.
