Abstract

The title compound, [Ni2(C22H46P2O2)2(CO)2], is located about a centre of inversion with the Ni0 atom within a distorted trigonal–planar geometry. The cyclohexyl rings are in the usual chair conformation with the 1,3-cis substituents equatorially oriented. No specific intermolecular interactions are noted in the crystal packing. A region of disordered electron density, most probably a disordered deuterobenzene solvent molecule, was treated using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148–155]. Its formula mass and unit-cell characteristics were not taken into account during refinement.
