  摘要：

  Me-2(Cl)SnCH2CH2PPh2 (1) reacts with Ni-II, pd(II) and Pt-II halides in molar ratio 2:1 forming the complexes [MX2{PPh2CH2CH2Sn(Cl)Me-2}(2)] (M=Ni, Pd, Pt; X=Cl, Br) (3-6, 9, 10) (7, 8: M = Ni; Br instead of Cl). The nickel complexes were isolated and characterized both as the planar (3, 5, 7) and the tetrahedral (4, 6, 8) isomer. Crystal structure analyses and NMR data indicate for the planar nikkel complexes 3, 5, 7 and [MCl2{PPh2CH2CH2Sn(Cl)Me-2}(2)] (9: M = Pd; 10: M = Pt) the existence of intra and intermolecular M-Hal ... Sn bridges. In a ligand:metal molar ratio of 3:1 the complexes [M+Cl{PPh2CH2CH2Sn-Cl2Me2}-{PPh2CH2CH2Sn(Cl)Me-2}(2)] (11: M = Pd; 12: M = Pt) are formed which represent intramolecular ion pairs. By dehaloge nation of [PdCl2{PPh2CH2CH2Sn(Cl)Me-2}(2)] (9) with sodium amalgam and graphite potassium (C8K), respectively, the palladacycles cis-[Pd{PPh2CH2CH2SnMe2}(2)] (13) and trans-[Pd(Cl)PPh2CH2CH2SnMe2{PPh2CH2CH2Sn(Cl)Me-2}] (14) are formed. From the compounds 1, 3, 9, 11, and 12 the crystal structures are determined. All compounds are characterized by H-1, P-31 and Sn-119 NMR spectroscopy.
