  摘要：

  摘要 2-喹啉甲基膦酸单乙酯 (2-mqmp) 的钯 (II) 配合物的热研究 (TG, DTA)：中性二卤化物加合物 Pd(2-mqmp) 2 X 2 ，离子对盐配合物 [2-Hmqmp] + [Pd(2-mqmp)X 3 ] - (X = Cl, Br) 和螯合二水合物 Pd(2-mqmp-H) 2 ·2H 2 O，已被用来确定这些具有生物学意义的复合物的分解特性化合物。复合物的热分解分两步进行：脱卤和配体去酯化，然后是复合热解，导致残留物被鉴定为元素、Pd 和 P 2 O 5 的混合物。红外光谱研究证实了这一点。没有稳定的中间产物，螯合物的情况下，除了相应的无水配合物，由于降解过程的复杂性和重叠，在热分解过程中被发现。将结果与 2-喹啉甲基膦酸二乙酯复合物的结果进行比较，并讨论了它们的细胞抑制活性。

  Palladium(II) coordination chemistry of monoethyl 2-quinolylmethylphosphonate

  摘要：

  The synthesis and some spectroscopic properties of the new palladium(II) complexes with monoethyl 2-quinolylmethylphosphonate (2-mqmp) have been reported. It was shown that the molecular or the ionic complexes could be isolated by reaction of 2-mqmp with PdX42-(X = Cl, Br) depending on the acidity of the aqueous reaction solution. The square planar dihalide complexes trans-Pd(2-mqmp)(2)X-2 with monodentate N-bonded ligand through the quinoline nitrogen were obtained at pH similar to 3.5. Under acidic conditions at pH < 3 the ion-pair salt complexes [2-mqmp H+][Pd(2-mqmp)X-3(-)] containing the protonated quinoline ligand as cation and the quinoliniummethylphosphonatetrihalopalladate complex as anion were isolated. These ionic complexes by heating in methanol were decomposed: the chloro complex to the molecular dichloropalladium adduct Pd(2-mqmp)(2)Cl-2, while its bromo analogue gave a mixture of the dibromopalladium adduct Pd(2-mqmp)(2)Br-2 and the ion-pair hexabromodipalladium salt complex [2-mqmp H+](2)[Pd2Br62-]. The chelate complex Pd(2-mqmp-H)(2) . 2H(2)O was isolated at pH > 6. In this compound 2-mqmp acts as a bidentate ligand through the quinoline nitrogen and the phosphonic acid oxygen. The new complexes were identified and characterized on the basis of elemental and thermogravimetric analysis, magnetic and conductance measurements, as well as by infrared and positive/negative-ion FAB-mass spectroscopic studies.
