Abstract

The cis compound crystallizes in the space group P2 1 /n with a=10.614, b=11.283, c=11.015A, β=93.33°, Z=4. The refinement converged to R=0.057. The trans compound crystallizes in Pbca with a=7.959, b=8.972, c=18.590A, Z=4. The refinement converged to R=0.031. The coordination geometry is sqaure-planar in both compounds. In the cis compound the Pt-Cl distances are in the range 2.321-2.327A and the Pt-S distances are both 2.273A. In the trans compound the Pt-Cl and Pt-S distances are 2.300 and 2.298A
