Bis{μ-cis-1,3-bis[(di-tert-butylphosphanyl)oxy]cyclohexane-κ2P: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 Ni0atom within a distorted trigonal–planar geometry. The cyclohexyl rings are in the usual chair conformation with the 1,3-cissubstituents 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 inPLATON[Spek (2009).Acta Cryst.D65, 148–155]. Its formula mass and unit-cell characteristics were not taken into account during refinement.
