Abstract The preparation, structures, and spectroscopic properties of several molecular complexes and a one dimensional chain are described. A one-dimensional trans-CrII(DMF)2(OTs)2}n (1) chain and mononuclear complexes of trans-[MII(OTs)2(DMF)4] (MII = Fe, 2; Co, 3) and [NiII(DMF)6][OTs]2 (4) stoichiometry are readily obtained from DMF/Et2O solutions containing the parent anhydrous tosylate salts
摘要描述了几种分子配合物和一维链的制备,结构和光谱性质。一维trans-CrII(
DMF)2(OTs)2} n(1)链和反式[MII(OTs)2(
DMF)4]的单核络合物(MII = Fe,2; Co,3) [NiII(
DMF)6] [OTs] 2(4)的
化学计量很容易从含有母体无
水甲
苯磺酸盐的
DMF / Et2O溶液中获得。从含有2的溶液中少量获得了
水合类似物反式[FeII(OTs)2(OH2)2(
DMF)2](5)。电子光谱表明,所有络合物在二甲基甲酰胺溶液中均采用八面体几何形状。室温敏感性数据表明,高自旋电子构型更适合于1(S = 2),2(S = 2)和3(S = 3/2),而4则采用S = 1自旋基态。
