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.

The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the...

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
