title: Bis{μ-cis-1,3-bis-[(di-tert-butyl-phosphan-yl)-oxy]cyclo-hexane-κ(2) P:P'}bis-[carbonylnickel(0)] including an unknown solvent molecule.
abstract: The title compound, [Ni2(C22H46P2O2)2(CO)2], is located about a centre of inversion with the Ni(0) atom within a distorted trigonal-planar geometry. The cyclo-hexyl rings are in the usual chair conformation with the 1,3-cis substituents equatorially oriented. No specific inter-molecular inter-actions 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.
