โœฆ Synopsis

The molecule of the title compound, C~16~H~18~P~2~, which was prepared by the reaction of dichloroethane with lithiated bis(diphenylphosphino)ethane, is disposed about a centre of symmetry. The 1,4-diphosphacyclohexane ring adopts a chair conformation with axial phenyl groups. The planes of the phenyl rings are orthogonal to the P...P axis.

The title complex, [Pt(C 16 H 18 P 2 ) 2 ](BF 4 ) 2 , possesses a crystallographically imposed center of symmetry occupied by a Pt II ion, which is coordinated by four P atoms from two 1,4diphenyl-1,4-diphosphacyclohexane ligands in a distorted square-planar geometry. ## Related literature The co
