Bis[μ-1,3-bis­(di­phenyl­phosphan­yl)propane-κ(2) P:P′]digold(I) tetra­chloridonickelate(II) diethyl ether monosolvate

The title compound, [Au(2)(C(27)H(26)P(2))(2)][NiCl(4)]·C(4)H(10)O, consists of a digold(I) complex cation, an [NiCl(4)](2−) complex anion and a diethyl ether solvent mol­ecule. Two 1,3-bis­(di­phenyl­phosphan­yl)propane (dppp) ligands bridge two Au(I) atoms, forming a metallacycle in which each of the Au(I) atoms is coordinated in a slightly distorted linear environment by two P atoms. In the complex anion, the Ni(II) atom is coordinated by four chloride ligands in a distorted tetra­hedral geometry. The complex cation and the complex anion form a cation–anion pair through two Au⋯Cl contacts of 3.040 (1) and 3.021 (2) Å. One of the phenyl groups of the dppp ligand is disordered over two positions with equal occupancies.
