Abstract

Two structurally and magnetically nonequivalent isomeric molecules, a cis-high-spin and a trans-low-spin isomer constitute the unit cell of a new iron(II) complex {cis-[FeL(B5)(NCS)(2)].trans-[FeL(B5)(NCS)(2)]}.CH(3)OH, , (L(B5) = N,N'-bis((2-N-methylimidazol-1-yl)methylene))-2,2-dimethylpropane-1,3-diamine); the synthesis, X-ray structure, and magnetic and Mössbauer study of this unique example of co-crystallised geometric, conformational and electronic isomers are reported.

摘要

两个结构和磁性不等价的异构分子，一个顺式高自旋异构体和一个反式低自旋异构体构成了一种新型铁（II）配合物{顺式-[FeL(B5)(NCS)(2)].反式-[FeL(B5)(NCS)(2)]}.CH(3)OH的晶胞，（L(B5)=N,N'-双((2-N-甲基咪唑-1-基)亚甲基))-2,2-二甲基丙烷-1,3-二胺）；报道了这种共结晶的几何、构象和电子异构体的独特例子的合成、X射线结构以及磁性和穆斯堡尔研究。
