摘要：

Ten palladium and platinum complexes each containing two chelating bis(diaminocarbene) ligands have been synthesized in a one pot-reaction from PdI2, PtI2 or K2PtCl4, a tenfold excess (forty equivalents) of isocyanide and 1,2- or 1,3-diamines. An X-ray investigation of [Pt{C(NHMe)NHCH(2)CH(2)NHCNHMe}(2)](PF6)(2) (8) revealed a stereochemistry with the two spiro-linked seven-membered metallacycles strongly bending out of the PtC4 coordination plane in opposite directions. In addition, three palladium bis-chelates with mixed amine/carbene bidentate ligands were obtained from reactions of PdI2 with only four equivalents of isocyanide and the diamine.
