stoichiometry yielded various bi- and tri-nuclear complexes. The homoleptic hexanuclear complexes [Pd(μ–SeCH2CH2X)2]6 (X = OH, COOH, COOEt), were obtained by reacting Na2PdCl4 with NaSeCH2CH2X. All these complexes have been fully characterized. Molecular structures of ethylselenolates containing hydroxyl and carboxylic acid groups revealed solid state associated structures through inter-molecular hydrogen bond
通过在甲醇或氨水中用NaBH 4还原相应的二硒化物,原位制备在β碳原子上具有官能团X(其中X = –OH,–COOH,–COOMe和–COOEt)的乙基硒酸钠。用[M 2 Cl 2(μ–Cl)2(公关3′)2 ](M = Pd或Pt;公关3′ = PMePh 2,P n Pr 3)在不同的化学计量下产生各种双核和三核配合物。通过使Na 2 PdCl 4与NaSeCH 2 CH 2 X反应,获得了均六价六核配合物[Pd(μ–SeCH 2 CH 2 X)2 ] 6(X = OH,COOH,COOEt)。 。含有羟基和羧酸基团的硒酸乙酯的分子结构通过分子间氢键相互作用揭示了与固态相关的结构。三核复合物,[Pd 3 Cl 2(μ–SeCH 2CH 2 COOH)4(P n Pr 3)2 ](3a)以船形形式放置,这与相应的甲酯配合物所观察到的椅子构象不同。硒化乙酯配体中β-官能团对钯和铂配合物的反
