摘要：

The coordination chemistry of the ligand bis[2-(3,5-dimethyl-1-pyrazolyl)ethyl]ether (L-1) was tested in front of Pd(II) and Pt(II). Complexes cis-[MCl2(L-1)] (M = Pd(II) and Pt(II)) were obtained, due to the chelate condition of the ligand and the formation of a stable 10-membered ring. The crystal structure of cis-[PtCl2(L-1)] was resolved by X-ray diffraction. Treatment of [PdCl2(L-1)] or [Pd(CH3CN)(4)](BF4)(2) with AgBF4 in the presence of L-1 gave the complex [Pd(L-1)(2)](BF4)(2). The initial cis-[PdCl2(L-1)] was recovered by reacting [Pd(L-1)(2)](BF4)(2) with an excess of NEt4Cl. Reaction of [Pt(CH3CN)(4)](BF4)(2) (generated in situ from [PtCl2(CH3CN)(2)] and AgBF4 in acetonitrile) with ligand L-1 yields complex [Pt(L-1)(2)](BF4)(2). (C) 2003 Elsevier B.V.
