Bi- and tri-nuclear palladium/platinum complexes of the types [MCl(ECH2CH2NMe2)(PR3)M'Cl-2(PR3)] (M, M'= Pd or Pt) and [PtCl(SeCH2CH2NMe2)(PR3)}(2)M' Cl-2] (M' = Pd or Pt; PR3 = PEt3 or PPr3n) have been prepared. All complexes were characterized 3 by elemental analysis, NMR (H-1, (31)p, Se-77, Te-125, Pt-195) data. The structures of [PdCl(SeCH2CH2NMe2)(PPh3)PtCl2(PPh3)] and [PtCl(SeCH2CH2NMe2)(PEt3)}(2)PtCl2] have been established by single crystal X-ray diffraction analysis. In the latter complex, three square planar platinum atoms are held together by the single bridging selenolate group in an almost linear chain arrangement. (c) 2007 Elsevier B.V. All rights reserved.
