✦ Synopsis

The crystal structure of the title compounds has been determined from X-ray data and refined to R = 0.048 for both compounds. Crystals of ( 1) are orthorhombic, space group Pna2 1 with cell dimensions a = 19.91(l), b = 14.98(l), c = 7.82(l) A. Crystals of (11) are monoclinic, space group P21/n with a = 11.07(l), b = 21.64(l), c = 10.0.5(l) 8, fl = 91.24(3)".

The

co-ordination of Pt(l1) is nearly square planar in both complexes. The Pt-cI bond lengths of 2.392(8) (1) and 2.387( 7) A (11) are equal within experimental errors, whereas the two chemically non-equivalent Pt-P bond lengths are significantly different in both (1) and (11). Their values are 2.320(9) A (tram to C,H,CHJ and 2.247(6) ,& (trans to Cl) for (1) and 2.326( 7) 8, (tram to C,FJ and 2.226(7) A (trans to Cl) for (11). No significant difference is found in Pt-C bond lengths (2.05(3) in (1) and 2.08(2) 8, in (II)), which however appear significantly longer than the values reported for Pt-C bond lengths having partial double bond character.
