Crystal and molecular structure of the 1 : 1 adduct between diphenyl sulphoxide and mercury (II) chloride

Abstract

The structure of the title compound was solved from diffractometer data by Patterson and Fourier methods and refined by least-squares techniques to R 5·0% for 2967 observed reflections. Crystals are triclinic, space group P, with unit-cell dimensions: a= 8·354(8), b= 8·304(7), c= 11·115(8)Å, α= 108·2(1), β= 100·3(1)°, γ= 102·3(1)°, Z= 2. The co-ordination around mercury involves the diphenyl sulphoxide molecule via the oxygen atom at 2·58 Å, two close chlorine atoms at 2·291 and 2·289 Å, and two chlorine atoms at neighbouring molecules at 3·230 and 3·284 Å. A sixth position is occupied by a phenyl ring at 3·51 Å.
