the Schiff base ligand occupying the basal sites while the chloride is axial. The complex [Mn(MEPHSALEN)(C2H5OH)2]- ClO4, where MEPHSALEN, C30H26N2O22-−, is the dianion of the product formed from the condensation of two moles of 2′-hydroxy- 5′-methylbenzophenone with one mole of 1,2-diaminoethane, crystallizes in the triclinic space group P with four molecules in a cell of dimensions a=9.492(3), b=17
描述了五种具有席夫碱配体的锰(III)配合物的合成,光谱和电化学表征。配合物[Mn(SALENCY)(H 2 O)(CH 3 CH 2 OH)] ClO 4的晶体结构,其中SALENCY C 20 H 20 N 2 O 2 2-为二价阴离子。通过X射线衍射技术已经确定了2摩尔的水杨醛与1摩尔的1,2-二氨基环己烷的缩合。该复合物在单斜系统的空间群P 2 1 / n中结晶,该空间群中有四个分子在一个尺寸的单元中a= 11.678(3),b= 15.654(3),c= 13.356(2),和β= 93.00(2)°。通过直接方法解析结构,并通过最小二乘法将其精炼为基于1484个独立观察到的反射系数,加权R因子的最终值为0.0437。该络合物大致为八面体,席夫碱配体占据四个基础位点,而轴向位点被一个水分子和一个乙醇分子占据。配合物[Mn(TETRAMESALEN)Cl],其中TETRAMESALEN,C
