An unusual heterobimetallic volatile compound [Pb2Co5(acac)14] was synthesized by the gas phase/solid-state technique. The preparation can be readily scaled up using solution approach. X-ray powder diffraction, ICP-OES analysis, and DART mass spectrometry were engaged to confirm composition purity of complex. is unique among large family lead(tin): transition metal = 2:1, 1:1, 1:2 β-diketonates...
The syntheses and molecular structures of two novel polynuclear copper(I)-purine-phosphine complexes are reported. The first one is a dinuclear [Cu2(μ-HL)2(μ-dppm)(η-dppm)2] complex (H2L is 8-mercaptotheophylline). The compound crystallizes in the triclinic system, space group P1h, with cell constants a ) 12.342(5) Å, b ) 15.255(5) Å, c ) 24.972(5) Å, R ) 74.31(2)°, â ) 78.62(2)°, γ ) 72.51(2)°...
Reaction of a phosphane-decorated benzenedithiol (pbdtH2) with coinage metal salts furnished polynuclear complexes [M2(pbdtH)2] (M=AuI) or [cat][M5(pbdt)3] (cat=unipositive cation, M=AgI, CuI), which were characterized by analytical and spectroscopic techniques single-crystal X-ray diffraction studies. Furthermore, double salt an anion [Ag5(pbdt)3(PPh3)]− that proved unstable in solution was cr...

A series of copper complexes (3-6) stabilized by 1,2,3-triazole-tethered N-heterocyclic carbene ligands have been prepared via simple reaction of imidazolium salts with copper powder in good yields. The structures of bi- and trinuclear copper complexes were fully characterized by NMR, elemental analysis (EA), and X-ray crystallography. In particular, [Cu2(L2)2](PF6)2 (3) and [Cu2(L3)2](PF6)2 (4...
