A novel tetranuclear copper(I) sulfanide complex with bis(diphenylphosphino)amine

W.-N. Zhao, L. Han and C.-C. Luo

Abstract: The title novel mixed [mu]2-SH- and [mu]3-SH-bridged tetranuclear copper(I) complex, cyclo-bis[[mu]2-bis(diphenylphosphino)amine]di-[mu]3-sulfanido-di-[mu]2-sulfanido-tetracopper(I) methanol disolvate, [Cu4(SH)4(C24H21NP2)2]·2CH3OH, has crystallographically imposed centrosymmetry and affords a neutral Cu4S4 core with a distorted step-like structure. The distances of 2.8458 (16) and 2.8179 (16) Å between copper(I) centres indicate the presence of ligand-supported Cu...Cu interactions. Strong N-H...O and O-H...S hydrogen bonds between the tetranuclear cluster and methanol solvent molecules result in a two-dimensional hydrogen-bonded supramolecular network. This complex is the first example of a coinage tetranuclear metal complex with mixed [mu]2-SH- and [mu]3-SH-bridged chromophores.

Formula: [Cu4(SH)4(C24H21NP2)2]·2CH4O
