N2 - Reaction between [NBu4][Pt(C6F5)3(dppm-? 1P)] and cis-[M(C6X5)2(thf)2] (M = Pt, Pd; X = F, Cl; thf = tetrahydrofuran) leads to dinuclear derivatives with dppm ligands bridging two metal centers: [NBu4][(C6F5)3-Pt{µ-Ph 2PCH2PPh(?2-Ph)}M(C6X 5)2] [X = F, M = Pt (1), M = Pd (2); X = Cl, M = Pt (3), M = Pd (4)]. The structural characterization of complex 1 by single-crystal X-ray diffraction (orthorhombic system, space group Fdd2, with a = 26.520(7) Å, b = 83.69(3) Å, c = 13.835(5) Å, V = 30706(11) Å3, and Z = 16) reveals two square-planar platinum(II) fragments sharing a dppm ligand with a ?2-phenyl-platinum interaction between a phenyl ring of the dppm ligand and one platinum center. This weak ?2-phenyl-platinum interaction can be easily displaced by addition of ligands such as CO (giving complex 5), PPh3 (6), or p-toluidine (7). The structure of 5 was determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group Pn, with a = 12.259(2) Å,b = 16.375(3) Å, c = 18.851(4) Å, ß = 100.99(3)°, V = 3714.8 A°3, and Z = 2. The complex consists of two square-planar platinum(II) fragments with the dppm ligand acting as a conventional bridge. © 1999 American Chemical Society.
