Di--chloro-bis[chloro(tricyclohexylphosphine-P)mercury(II)]

L. Liu, Q.-F. Zhang and W.-H. Leung

Abstract: In the title compound, [Hg₂Cl₄(C₁₈H₃₃P)₂], there are two independent centrosymmetric Hg^II dimers, the asymmetric unit containing half of each. The coordination about each Hg atom is highly distorted tetrahedral, three sites being occupied by one terminal and two bridging Cl atoms, and the remaining site by the P atom of a tricyclohexylphosphine ligand (PCy₃). The Hg atoms in the dimers are 3.792  (3) and 3.940  (3)  Å apart and are thus non-bonded.
