title: A novel tetranuclear copper(I) sulfanide complex with bis(diphenylphosphino)amine.
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, [Cu(4)(SH)(4)(C(24)H(21)NP(2))(2)].2CH(3)OH, has crystallographically imposed centrosymmetry and affords a neutral Cu(4)S(4) core with a distorted step-like structure. The distances of 2.8458 (16) and 2.8179 (16) A 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.
