Abstract
Reaction between a mixture of cis-trans-[PtCl2(SMe2)(2)] and 1 eqiv. AsPh3 in chloroform gives Cis-[PtCl2(SMe2)(AsPh3)] crystallizing in P2(1)/n with a = 10.397(2), b = 14.876(3), c = 13.956(3) Angstrom, beta = 90.86(3)degrees and Z = 4. Selected geometrical parameters are Pt-As 2.3531(10), Pt-S 2.262(2), Pt-Cl (trans to S) 2.301(2), Pt-Cl (trans to As) 2.328(2) Angstrom and S-Pt-As 88.85(6), S-Pt-Cl(2) 90.77(8), As-Pt-Cl(1) 91.07(6) and Cl-Pt-Cl 89.42(7)degrees, cis-[PtCl2(AsPh3)(2)].CHCl3 crystallizes in P2(1)/c with a = 20.557(4), b = 9.5951(19), c = 20.147(4) Angstrom, beta = 96.77(3)degrees and Z = 4. Selected geometrical parameters are Pt-As(1) 2.3599(9), Pt-As(2) 2.3770(9), Pt-Cl(1) (trans to As(1)) 2.3515(18), Pt-Cl(2) (trans to... (More)

By comparison with related structures from the literature the following trans influence series was established PMe2Ph > PPh3 > AsPh3 approximate to SbPh3 > Me2SO approximate to SMe2 approximate to SPh2 > NH3 approximate to olefin > Cl- > MeCN.
