CRYSTAL-STRUCTURE AND MOLECULAR-STRUCTURE OF CIS-BIS[DICYCLOHEXYLPHOSPHINO-N-PHENYL(THIOFORMAMIDO)]PALLADIUM(II) - CIS-[PD((C-C6H11)(2)PC(S)=N(C6H5))(2)]

The crystal structure of cis-[Pd{(c-C6H11)2-PC(S) = N(C6H5)}(2)] has been determined at room temperature. The yellow crystals are monoclinic, space group C2/c with unit cell dimensions a = 19.601(2) Angstrom, b = 8.2633(8) Angstrom, c = 23.627(1) Angstrom, beta = 94.218(6)degrees, Z = 4, C38H54N2P2PdS2 and D-x = 1.342 Mg m(-3). The structure was solved by direct methods and refined by a full-matrix least-squares procedure to final R = 0.040 using 2331 reflections. The molecule is disposed about a crystallographic two-fold axis and the (c-C6H11)(2)PC(S) = N(C6H5) ligand chelates the palladium atom via the thiolato S atom and the phosphino P atom such that the two sulphur atoms are cis to each other; important parameters: Pd-S 2.347(1) Angstrom, Pd-P 2.279(1) Angstrom, and S-Pd-S 100.27(7)degrees.
