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

The title complex, [Au-2(C17H11N)(2)(C12H10P)]ClO4 center dot C2H3N, contains two Au-III 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 pi-pi stacking interactions between neighbouring molecules (the interplanar separations between two neighbouring dpp units are 3.40 and 3.57 angstrom). The intramolecular Au center dot center dot center dot Au separation is 3.788(5)angstrom. The crystal structure shows weak intermolecular C-H center dot center dot center dot O and CH center dot center dot center dot N hydrogen bonds involving an O atom of the perchlorate counter-ion and the N atom of the acetonitrile solvent molecule, respectively.
