[1,2-Bis(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane-2?(2) P,P']di-?-chlorido-1:2?(4) Cl:Cl-di-chlorido-1?(2) Cl-dimercury(II).

ABSTRACT: The title compound, [Hg2Cl4(C26H54B10P2)], was synthesized by the reaction of 1,2-bis-(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with HgCl2. Both Hg(II) atoms show a distorted tetra-hedral coordination geometry, provided by the two bridging chloride anions and the P atoms of the diphosphanyl ligand for one metal atom, and by two bridging and two terminal chloride anions for the other. The five-membered HgP2C2 chelate ring assumes an envelope conformation, with the Hg(II) atom displaced by 0.1650?(5)?Å from the mean plane of the other four atoms (r.m.s. deviation = 0.002?Å). In the crystal, B-H?Cl interactions link the molecules, forming a supramolecular chain along the a-axis direction.
