Abstract A luminescent bimetallic Au I complex comprised of N ‐heterocyclic carbene (NHC) and carbazole (Cz) ligands, that is, (NHC’)Au(NHC)AuCz has been synthesized studied. Both ligands in the act as electron acceptors tandem to increase energy separation between ground excited state, which is higher than those found either monometallic analogue, (NHC)AuCz (NHC’)AuCz. coplanar geometry designed into ensures sufficient electronic coupling π‐orbitals impart a strong oscillator strength...
The mesoionic compound (1,4-diphenyl-1,2,4-triazol-4-ium-3-yl)phenylazanide, commonly referred to as Nitron, has been employed a "crypto-NHC" afford 1,2,4-triazolylidene compounds of nickel, palladium, and iridium. Specifically, Nitron reacts with NiBr2, PdCl2, [Ir(COD)Cl]2 the N-heterocyclic carbene complexes (NitronNHC)2NiBr2, (NitronNHC)2PdCl2, (NitronNHC)Ir(COD)Cl, respectively. lattermost (i) CO dicarbonyl (NitronNHC)Ir(CO)2Cl (ii) CO, in presence PPh3, monocarbonyl...
The reactions of bis(2-pyridylthio)methane with Me2Zn and Zn[N(SiMe3)2]2 afford [Bptm]ZnMe [Bptm]ZnN(SiMe3)2, thereby providing access to a variety other [Bptm]ZnX derivatives, including the zinc hydride complex [Bptm]ZnH, which serves as catalyst for reduction CO2 carbonyl compounds via hydrosilylation hydroboration.
The zinc hydride compound, [Tptm]ZnH, may achieve the reduction of CO2 by (RO)3SiH (R = Me, Et) to methanol oxidation level, (MeO)xSi(OR)4-x, via formate species, HCO2Si(OR)3. However, because insertion into Zn-H bond is more facile than HCO2Si(OR)3, conversion HCO2Si(OR)3 level only occurs a significant extent in absence CO2.

The bis(2-pyridylthio)methyl ligand, [Bptm], has been employed in the synthesis of {[Bptm]Zn(μ-F)}2, a rare example an organozinc fluoride compound. dimeric nature which possesses uncommon [Zn(μ-F)]2 motif, contrasts with monomeric structures reported for other halide derivatives, [Bptm]ZnX (X = Cl, Br, I); this difference is supported by density functional theory calculations indicate that derivative favors form bridging ligands, whereas derivatives favor terminal ligands. {[Bptm]Zn(μ-F)}2...
Metal complexes of 3,5-diisopropylsalicylate are reported to have anti-inflammatory and anti-convulsant activities. The title binuclear copper complex, [Cu 2 (C 13 H 17 O 3 ) 4 6 OS) ] or [Cu(II) (3,5-DIPS) (DMSO) ], contains two five-coordinate atoms that bridged by four ligands capped axial dimethyl sulfoxide moieties.
