摘要

Dicyanide building block cis-Fe(phen)2(CN)2 and [MnIII(salen)](ClO4) have been used to design and synthesize a cyanide-bridged complex, resulting in a heterobimetallic one-dimensional (1D) zigzag chain complex 1, [cis-Fe(phen)2(CN)2Mn(salen)](PF6) (phen = 1,10-phenanthroline, salen = N,N΄-ethylenebis-(salicylideneaminato) dianion). Single-crystal X-ray diffraction analysis shows complex 1 crystallizes in the monoclinic P21/c space group and the asymmetric unit contains one [-NC-Fe(phen)2(-CN)-MnIII-(salen)-]+ cation and one PF6- anion. In the cationic structure of 1, each FeII(phen)2(CN)2 connects two [MnIII(salen)]+ with two cyanide groups in a cis-conformation, and in turn each [MnIII(salen)]+ unit links two FeII(phen)2(CN)2 building blocks in a trans-conformation, resulting in a 1D [-NC-FeII-CN-MnIII-]n chain. Furthermore, the electronic absorption spectra and electrochemical and magnetic properties of complex 1 have also been studied.

Abstract：将二氰基结构单元 cis-Fe(phen)2(CN)2和[MnIII(salen)](ClO4)反应，得到一个氰桥一维（1D）zigzag链异核化合物1，[cis-Fe(phen)2(CN)2Mn(salen)](PF6) （phen = 1,10-邻菲咯啉，salen = N,N’-亚乙基双（亚水杨基）阴离子）。 X-射线衍射分析表明化合物1是单斜晶系P21 /c空间群，每个不对称单元含有一个[-NC-Fe(phen)2(-CN)-MnIII-(salen)-]+ 阳离子和一个PF6-阴离子。化合物1的阳离子结构中每个 FeII(phen)2(CN)2单位通过两个氰基以顺式构象连接两个[MnIII(salen)]+ 结构单位，并且每个[MnIII(salen)]+ 单元以反式构象连接两个FeII(phen)2(CN)2 结构单元，得到一维 [-NC-FeII-CN-MnIII-]n 链。此外，我们还研究了化合物1的电子吸收光谱、电化学和磁性质。
