Abstract
The crystal structure of a pale-yellow complex [(Ph3PCHC(O)C6H4Cl)·HgI2·DMSO] was determined by the X-ray diffraction method. All atoms occupy general positions in the monoclinic space group, P21/c and have the following unit-cell dimensions: a = 15.5243(7)Å, b = 10.0196(5)Å, c = 20.0731(10)Å, β = 100.292(4)°, Z = 4 and V = 3072.1(3)Å3.
