Summary: The synthesis and characterization of a series of divalent Ge and Sn compounds with an ambiphilic nature is described. These compounds are obtained by forcing divalent group 14 elements into a planar geometry using a sterically constrained pincer-type ligand. The reactions of these compounds with various Lewis bases and acids are investigated, showing formation of both dimeric and monomeric species.

Summary: Calculations based on density functional theory were used to analyze the energy barrier for the formation of terminal metal-oxo from metal hydroperoxo species with buea ligand. The results showed that the energy barriers for the cleavage of the OMIDLINE HORIZONTAL ELLIPSISO bond were higher for late transition metals compared to early transition metals, supporting the concept of the oxo wall.

Summary: A new oxo-bridged chromium-molybdenum heterometallic complex, O-CrMoHC, was synthesized by a solvothermal reaction. The complex exhibits anisotropic conductivity in single crystals, with higher electrical conductivity along the [01-1] direction compared to the [100] direction. This is the first report of anisotropic conductivity observed in a monomeric heterometallic complex single crystal.

Summary: The structure, bonding, and reactivity of nitrogen-containing beryllium compounds were investigated at the theoretical level. It was found that the best bonding representation is an interaction between Be+ and the ligands. Both compounds exhibited high proton and hydride affinity, indicating their ambiphilic reactivity. These compounds showed exothermic reaction energy for adduct formation with electron donor ligands.

Summary: We report two unique thorium arenide complexes prepared by reduction of a Th-IV-siloxide complex in presence of naphthalene. The stored electrons in these complexes enable the reduction of a broad range of substrates. The reactivity can be tuned by the arenide binding mode, as shown in the reaction of complex 1 with diazoolefin IDipp=CN2.

Summary: This study reports three palladium terminal imido complexes with singlet ground states. UV-vis-NIR electronic spectroscopy, high-level computations, and reactivity studies suggest significant palladium(0) singlet-nitrene character. Although the aliphatic nitrene complexes cannot be isolated in pure form, the aryl congener can be characterized by various techniques. The ambiphilic nature of these complexes allows them to catalyze various reactions at or below room temperature.

Summary: Late-transition-metal oxo and imide complexes are important in catalytic functionalization and activation of small molecules. The use of lower coordination numbers and pseudotetrahedral geometries has been seen as a way to stabilize otherwise highly reactive species, but the bonding structure in d(6) complexes in this geometry remains ambiguous. Recent experimental evidence suggests significant empirical differences between these complexes and other triply bonded compounds.

Summary: Four new structurally similar dinuclear oxorhenium(V) complexes have been synthesized and characterized, showing little variation in spectroscopic features. All complexes exhibit a bent Re-O-Re core and distorted octahedral coordination geometry. A reversible one-electron electrochemical process is observed at approximately 0.84 V vs. Fc(+)/Fc in all four complexes, with a slight destabilization of the oxidized Re(VI) center when changing the terminal halide from chloride to bromide.

Summary: A new synthesis method for (Me2PCH2BMe2)(2) and (Ph2PCH2BMe2)(2) was reported, which showed different reactivity at room temperature. The ligand precursor (Me2PCH2BMe2)(2) did not react with [{M(mu-Cl)(cod)}(2)] or [PtCl2(cod)], while the phenyl-substituted analogue (Ph2PCH2BMe2)(2) reacted readily with [{M(mu-Cl)(cod)}(2)] to generate the desired products.

Summary: Neptunium, the first artificially synthesized actinide, has been less studied compared to its famous neighbors uranium and plutonium. This study reports the synthesis, isolation, and characterization of a stable molecular neptunium(V)-mono(oxo) triamidoamine complex, demonstrating the possibility of stabilizing and studying high-oxidation-state transuranic complexes with a single metal-ligand bond.

Summary: This research reports the preparation, spectroscopic characterization, and reactivity studies of a Co(IV)-oxo complex with an N4-macrocyclic coligand. Experimental data show the formation of a Co(IV) intermediate and the existence of the oxo group, supported by DFT calculations and spectroscopic techniques analyzing the structure.

Summary: The primary noncovalent interaction in frustrated Lewis pairs involves lone pair/π interactions between the terminal MX bond and the aromatic C6F5 ring of B(C6F5)3. Energy decomposition analyses show that FLPs and classical adducts can be differentiated by the ratio of covalent-to-noncovalent contributions to the total interaction energy. This study suggests that similar noncovalent interactions exist in both transition-metal and main-group FLPs, especially when using Lewis acids such as B(C6F5)3.

Summary: Hybrid functionals with modest amounts of included Hartree-Fock exchange are most effective at matching experimentally determined lambda(max) in organic dyes, but the characterization of electronic excitations with charge-transfer character is highly sensitive to the chosen functional.
