Synthesis and characterization of cationic [tris(pyrazolyl)methane]copper(I) carbonyl and acetonitrile complexes

The reaction of [Cu(NCMe)4]PF6 with equimolar amounts of the tris(substituted-pyrazolyl)methane ligands HC(3,5-Me2pz)3, HC(3-Phpz)3, and HC(3-Butpz)3 yields the respective salts {[HC(3,5-Me2pz)3]Cu(NCMe)}PF6, {[HC(3-Phpz)3]Cu(NCMe)}PF6, and {[HC(3-Bu4pz)3]-Cu(NCMe)}PF6. These complexes are unusually resistant toward reaction with dioxygen. These acetonitrile complexes react with carbon monoxide to yield the stable complexes {[HC(3,5-Me2pz)3]Cu(CO)}PF6, {[HC(3-Phpz)3]Cu(CO)}PF6, and {[HC(3-Butpz)3]Cu(CO)}PF6, respectively. The solid-state structures of {[HC(3-Butpz)3)]Cu(NCMe)}PF6·CH 2Cl2 and ([HC(3-Butpz)3]Cu(CO)}PF6 have been determined by X-ray crystallography. The structures are very similar, with the Cu-N distances to the donor atoms of the HC(3-Butpz)3 ligand 0.03 A? shorter in the carbonyl complex.

Syntheses and structures of tetranuclear and hexanuclear copper(I) complexes with iminomethanethiolato bridges derived from isothiocyanate

Methylisothiocyanate, MeN=C=S, in ethanol reacted with copper(I) giving a tetranuclear complex [Cu{μ3-SC(=NMe)(OEt)}]4 (1). Similar reaction of allylisothiocyanate, CH2=CHCH2N=C=S, and copper(I) in methanol gave ahexanuclear complex, [Cu{μ3-SC(=NC3H5)(OMe)}]6 (2). They show tetrah edral Cu4 and octahedral Cu6 cores, respectively.There are two structural similarities in both complexes: (i) a thiolato moiety [-N=C(S(-))-] which bridges three copper atoms with a monodentate nitrogen atom and a bridging sulphur atom and (ii) a trigonal planar geometry for copper (I) coordinated by one nitrogen atom and two sulphur atoms. Each iminomethanethiolato ligand is formed in situ in solvent. (1)H NMR shows the reaction is initiated by a coordination of an isothiocyanate to copper(I).
