| Abstract: | Summary The structure of PtCl(CF3)(cis-Ph2PCH=CHPPh2), has been determined from three-dimensional x-ray data. The complex crystallizes in the monoclinic system, space group C2h5-P21/n witha=19.781(6),b=15.024(5),c=8.547(3) Å, =93.2(1)° andZ=4. Least-squares refinement has led to a value of the conventional R index (on F) of 0.055 for the 3199 independent reflections having I 2.5 (I). The complex is a typical square-planar PtII complex with structural parameters: Pt-P, 2.275(4) (a)trans to CF3 and 2.236(4) (b)trans to Cl, Pt-Cl, 2.346(4), Pt-C(F), 2.188(8), C(A) = C(B), 1.38(2) Å; Cl-Pt-P(1), 91.1(1), P(1)-Pt-P(2), 86.2(1)°. |
