摘要：
Di-mu-chlorobis{(eta(3)-methallyl)palladium(II)} (1) reacts with two equivalents of 1'-(diphenyl-phosphanyl)ferrocene-1-carboxylic acid (Hdpf) and rac-[2-(diphenylphosphanyl)ferrocen-1-yl] acetic acid (rac-Hpfa) to give complexes with P-monodentate phosphanylcarboxylic ligands: [PdCl(eta(3)- CH2C(Me)CH2)(L-kappa P)], L = Hdpf ( 2) and rac-Hpfa ( 4). Similar reactions with the corresponding carboxylate salts (Kdpf and Kpfa) afford, respectively, an ill-defined polymer formulated tentatively [{Pd(eta(3)-CH2C(Me)CH2)(dpf)}(n)] (3) and the molecular chelate complex [PdCl(eta(3)-CH2C(Me)CH2)(pfa-kappa O-2,P)] ( 5), which crystallizes as a monohydrate. All compounds were studied by spectral methods (IR and NMR) and the solid-state structures of 2, 4, and 5(.)H(2)O were determined by single-crystal X-ray diffraction.
