formula [MCl2L2] and one dinuclear complex trans-[Pd2Cl4(3a)2] were synthesized and their isomerization behaviour in solution was studied. The complexes were characterized by 1H, 13C, 31P and 195Pt NMR spectroscopy, mass spectrometry and far-IR spectroscopy. The X-ray structures of all complexes with 3a or 3b have usual slightly distorted square-planar geometry on the metal ion. Salts of phosphonic acids
两种三苯基膦衍生物,[4-(二苯基膦基)苄基]膦酸二乙酯(3a)和[5-(二苯基膦基)-1,3-亚苯基]二亚甲基}双(膦酸酯)(3b),以及相应的游离酸4a和4b准备好了。这些配体通过1 H,13 C和31 P NMR光谱学和质谱法表征。全套[MCl 2 L 2 ]的Pd(II)和Pt(II)配合物和一个双核配合物反式-[Pd 2 Cl 4(3a)2合成,研究了它们在溶液中的异构化行为。通过1 H,13 C,31 P和195 Pt NMR光谱,质谱和远红外光谱对复合物进行表征。具有3a或3b的所有配合物的X射线结构在金属离子上通常具有略微扭曲的方平面几何形状。膦酸4a和4b的盐及其络合物可自由溶于水溶液;因此,它们可能在水相或双相催化中有用。
