Dichlorido(4,4′-di-tert-butyl-2,2′-bi-pyridine-2 N,N′)gold(III) tetrachlorido-aurate(III) acetonitrile solvate

Abstract

In the title compound, [AuCl2(C9H12N)2][AuCl4]·C2H3N, there is a mirror plane passing through Au and the central C - C bond of the bipyridyl ligand in the cation, and through Au and two Cl atoms of the anion. A cis-AuCl2N2 square-planar geometry for the cation and a square-planar AuCl4 geometry for the anion result. The two C atoms and the N atom of the acetonitrile mol-ecule all have m site symmetries. In the crystal structure, weak C - H⋯Cl inter-actions may help to establish the packing.
