The reaction of Li (Y = CH or N) with (M = Ni or Pd; X = Cl or Br; L = PPh3, PMe2Ph or PEt3) has been studied.With Y = CH only palladium derivatives were obtained; subsequent reaction with Grignard reagents, MgBr(R), gave (R = mesityl or o-tolyl).With Y = N, nickel and palladium complexes, , were obtained only with PEt3.The compounds or 2> were formed using PPh3 or PMe2Ph instead of PEt3.Treatment of these complexes with HBF4 yielded the corresponding cationic complexes containing the neutral chelate ligand.These complexes have been characterized by IR, 1H and 31P NMR spectroscopy.The complex crystallizes in the monoclinic space group C2/c, with a = 18.416(6), b = 11.702(4), c = 27.620(9) Angstroem, β = 93.50(4) deg and Z = 8.The P-N bond distances 1.64-1.65 Angstroem are consistent with delocalization of the negative charge in the anionic ligand.The P***P distance, 2.440 Angstroem, is close to a single P-P bond length.
