Crystal and molecular structure of dithiocyanatobis(triphenylphosphine)-mercury(II)

Abstract

The crystal and molecular structure of the title compound has been determined from three-dimensional X-ray data. Crystals are monoclinic, space group P2₁/c, a= 17·385(9), b= 10·581 (4), c= 19·304(5)Å, β= 91·41 (6)°, and Z= 4. The structure was solved from diffractometer data by the heavy-atom method and refined by least-squares procedures to R 0·048 for 2769 observed reflections. The cell contains monomeric molecules and the mercury atom is in a distorted tetrahedral environment, as previously suggested on the basis of the i.r. spectrum. Bond lengths are: Hg–S 2·565 and 2·577, and Hg–P 2·487 and 2·484 Å.
