Abstract
The structure of the title compd. was detd. at room temp. from 3-dimensional x-ray data collected by counter methods and refined by least-squares techniques to a final R of 0.059 based on 3897 observations above background. The compd. crystd. in the monoclinic space group P21/a with a 19.725(4), b 16.247(2), c 15.321(2) Å and 105.85(2)°, Z = 4. The Pt atom has square-planar coordination with Pt-P(1) = 2.289(6), Pt-P(2) = 2.251(7), Pt-Cl = 2.353(7), and Pt-N(1) = 2.11(2) Å. The aryldiazene moiety lies in a plane roughly perpendicular to the coordination plane and its Ph groups are twisted to relieve steric interactions with the adjacent phosphine Ph groups.
