Popis:	Several new transition metal complexes of the cyclopentadienyl ylides (CpPPh3, CpSMe2, and CpPy are reported. Reactions of CpSMe2 with MnCl2, FeCl2, CoCl2 and NiX2 (where X=d or Br) leads to complexes in which the ylide:metal halide stoichiometry is 1:1. These complexes are assigned sandwich structures. Reaction of Pd(NO3)2 with CpSme2 yields a very air-sensitive compound having a unique (CpSMe2)3 Pd(NO3)2 stoichiometry. With HgX2 the CpSMe2 HgX2 (where X=Cl, Br, I) derivatives are formed; bonding of the mercury is shown for the iodide derivative to be at C-3 of the cyclopentadienyl ring. Reaction of CpPPh3 with FeCl2 produces two derivatives which appear to have stoichiometrieg unique in iron metallocene chemistry: (CpPPh3)Fe2 Cl4 and (CpPPh3)Fe2Cl4.
