(μ-Diphenylphosphanido-κ2P:P′)bis[2,2′-(pyridine-2,6-diyl)diphenyl-κ3C1,N,C1′)gold(III)] perchlorate acetonitrile solvate

Abstract

The title complex, [Au2(C17H11N)2(C12H10P)]ClO4·C2H3N, contains two AuIII atoms bridged by a diphenylphosphanide ligand. Each Au atom is in a square-planar environment coordinated by diphenylphosphanide and 2,6-diphenylpyridine ligands. There are weak π–π stacking interactions between neighbouring molecules (the interplanar separations between two neighbouring dpp units are 3.40 and 3.57 Å). The intramolecular Au...Au separation is 3.788 (5) Å. The crystal structure shows weak intermolecular C—H...O and C—H...N hydrogen bonds involving an O atom of the perchlorate counter-ion and the N atom of the acetonitrile solvent molecule, respectively.
