The reactions of lithium derivatives of diphosphanes R(2)P-P(SiMe(3))Li (R = (t)Bu, (i)Pr, Et(2)N and (i)Pr(2)N) with [(R'(3)P)(2)PtCl(2)] (R'(3)P = Et(3)P, Et(2)PhP, EtPh(2)P and p-Tol(3)P) proceed in a facile manner to afford side-on bonded phosphanylphosphinidene complexes of platinum [(eta(2)-P=R(2))Pt(PR'(3))(2)]. The related reactions of Ph(2)P-P(SiMe(3))Li with [(R'(3)P)(2)PtCl(2)] did not yield [(eta(2)-P=PPh(2))Pt(PR'(3))(2)] and resulted mainly in the formation of [{(R'(3)P)(2)Pt}(2)P(2)], Ph(2)P-PLi-PPh(2), (Me(3)Si)(2)PLi and (Me(3)Si)(3)P. Crystallographic data are reported for the compounds [(eta(2)-P=R(2))Pt(p-Tol(3)P)(2)] (R = (t)Bu, (i)Pr, ((i)Pr(2)N)(2)P) and for [{(Et(2)PhP)(2)Pt}(2)P(2)].

Key indicators: single-crystal X-ray study; T = 120 K; mean (C-C) = 0.007 Å; R factor = 0.025; wR factor = 0.089; data-to-parameter ratio = 18.7.In the title compound, [PtCl 2 (C 10 H 15 P) 2 ], the Pt atom adopts a slightly distorted square-planar geometry. The phenyl rings form dihedral angles of 82.21 (11) and 79.98 (11) with the PtCl 2 P 2 mean plane. The crystal structure is stabilized by weak intra-and intermolecular C-HÁ Á ÁCl hydrogen bonds.
