Summary: Recent research has demonstrated the promising utility of transition metal complexes with M-E bonds stabilized by multidentate ligands, where E represents a main group metal or metalloid element. Main group metal and metalloid ligands provide unique electronic and steric environments to transition metals, leading to remarkable catalytic activity and product selectivity. This perspective highlights the potential of these compounds as a new class of supporting ligands for transition metal catalysts in synthetic chemistry.

Summary: This study explores the bonding interactions and electronic structure of a diphosphine pincer ligand with a N-heterocyclic phosphenium/phosphido central moiety and nickel. The activation of O-H bonds across the Ni-PNHP bond and the successful installation of a P-H bond on the NHP unit are demonstrated.

Summary: Despite the great progress achieved on phosphorescent or photoactive complexes of Earth-abundant transition metals, examples for phosphorescent heavy main group element complexes are rare, especially for group 14 complexes in the oxidation state +II. This study on tin(II) and lead(II) complexes provides unprecedented insight in the excited state energy landscape of tetrel(II) complexes and offers rational design principles for tetrel(II) complexes with long-lived phosphorescence.

Summary: A series of novel tetracyano-substituted dihydrotetraaza[14]annulene analogues were synthesized in a simple and convenient way, and their complexes with nickel(II), copper(II) and palladium(II) ions were characterized, with X-ray structures determined for seven compounds. X-ray analysis revealed relatively short distances between tetraazamacrocyclic rings due to strong pi-pi interactions. Some of the synthesized compounds can be easily modified to attach reactive groups, making them promising components for future pi-interaction based supramolecular systems.

Summary: More than three decades ago, isolable T-shaped planar pnictogen compounds R(3)Pn were reported and have gained increasing attention recently. However, T-shaped planar group 14 anions, which are isoelectronic to R(3)Pn, remain unknown. In this study, the synthesis, characterization, and reactivity of the first crystalline T-shaped planar group 14 anion 4 with a trinitrogen pincer ligand are reported. DFT calculations suggest that the tricoordinate germanium center exhibits both an unoccupied 4p orbital and two lone pairs of electrons, enabling nucleophilic attack and facile oxidation to produce unprecedented organic anions with terminal Ge (sic) Ch (Ch = S or Se) double bonds.

Summary: Bidentate aminopyridinato ligands, particularly 2-aminopyridines, have become popular in coordination chemistry as alternatives to cyclopentadienyl ligands. The easy modifiability and fine-tuning of electronic effects of 2-aminopyridines have enabled researchers to control metal complexes properties. By introducing bulky steric bulks, the ligands can stabilize transition metals in unusually low oxidation conditions and even stabilize metal-metal quintuple bonds. These ligands have also found broad application in homogeneous catalysis in recent years.

Summary: Group 11 thin films are desirable for interconnects in microelectronics. Monovalent Cu, Ag, and Au 1,3-di-tert-butyltriazenides show potential as single-source precursors for vapor deposition, with comparable thermal stability and volatility to current state-of-the-art precursors. Solution thermolysis of these triazenides yields polycrystalline films of elemental Cu, Ag, and Au.

Summary: Heterobimetallic complexes have diverse structures and reactivities, and can serve as single-source precursors for synthesizing binary intermetallic compounds. This study investigates the binding energies of phosphorous-based ligands and the reactivity of heterobimetallic complexes, showing that stronger binding ligands inhibit access to active sites. The findings provide insights into ligand-binding energetics and predict reactivity as precursors and catalysts.

Summary: Low valent group 14 compounds with diazaborolyl substituents exhibit unique structures and reactivity due to the combination of sigma-electron donation and steric hindrance. The modulation of the HOMO-LUMO gap by the diazaborolyl substituents results in novel reaction patterns in the activation of small molecules and inert chemical bonds.

Summary: An unprecedented anionic pincer ligand with pendant phosphazene arms has been synthesized, which can stabilize main-group and transition metal complexes. The phosphazene arms strongly coordinate to the metal centers, while the central amide group alternatively donates one or two pairs of electrons to bind with different metal centers.

Summary: Thiazetidin-2-ylidenes have been designed as smaller analogs of thiazol-2-ylidenes with high singlet stability and large nucleophilicity. The possible existence of these carbenes has been established by synthesizing and crystalizing compounds with NHC -> N+<-(thiazetidin-2-ylidene) coordination bonds.

Summary: A N-aryloxide-amidine ligand (H3L) was synthesized from 2-(aminomethyl)-6-(tert-butyl)phenol in two steps, which integrates phenoxide and amidine ligands through methylene linkers. The coordination modes of the resulting complexes depend on the radius of the metal ions. The ligand can form a dimer (LMIV-Cl)2 with group 4 metal chloride (MCl4)-Cl-IV, and the coordination mode of the amidinate moiety can change from bidentate chelating to bimetallic bridging coordination.

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.
