Abstract The reactions of [ReOCl4]− with Schiff base ligands derived from salicylaldehyde and 1,5-diamino- pentane (H2L1a), -hexane (H2L1b), -heptane (H2L1c) or diethylentriamine (H3L2) have been investigated. The complexes ReOCl2(EtOH)HL1n (I) (n=a, b or c), Re2O2(MeOH)2Cl4HL2 (II), ReOClL1n (III) and ReOL2 (IV), have been synthesized and characterized with the usual physicochemical measurements.
摘要研究了[ReOCl4]-与水杨醛和1,5-二氨基戊烷(H2L1a),-己烷(H2L1b),-庚烷(H2L1c)或二乙三胺(H3L2)衍生的席夫碱配体的反应。ReOCl2(EtOH)HL1n(I)(n = a,b或c),Re2O2(MeOH)2Cl4HL2(II),ReOClLnn(III)和ReOL2(IV)的配合物已合成并通过常规理化测量进行了表征。ReOL2的晶体结构是通过单晶X射线方法确定的。晶体是单斜晶,空间群P21 / c,a = 9.470(7),b = 9.358(8),c = 21.859(12)A,β= 99.23(8)16°,Z = 4。X射线衍射提供了5601次观察到的反射(高达2⊖= 60°),并且该结构已经通过全矩阵最小二乘法改进为R = 0.061。单体结构由扭曲的八面体ReOL2单元组成。N3O2五齿配体的一个氧原子位于trans-氧代氧键上,而其余四个配
