Abstract

The asymmetric unit of the title compound, [Fe(CHN)][C{C(CN)}], contains an iron-bipyridyl unit and one third of two crystallographic independent tris-(di-cyano-methyl-idene)methane-diide units. As a result of crystallographic site symmetry the ratio of cations to anions is 1:1. The tris-(2,2'-bi-pyridine)-iron(II) cation has threefold symmetry. The two crystallographic independent tris-(di-cyano-methyl-idene)methane-diide ions are disordered over two atomic sites having equal occupancy. The anions have 3 symmetry. In the crystal, hydrogen bonds between cations and anions form complex layers parallel to (001). These are supplemented by hydrogen bonds perpendicular to the former, leading to a three-dimensional network.

摘要

标题化合物[Fe(CHN)][C{C(CN)}]的不对称单元包含一个铁-联吡啶单元以及两个晶体学独立的三（二氰基亚甲基）甲烷二亚胺单元的三分之一。由于晶体学位点对称性，阳离子与阴离子的比例为1:1。三（2,2'-联吡啶）铁（II）阳离子具有三重对称性。两个晶体学独立的三（二氰基亚甲基）甲烷二亚胺离子在两个占有率相等的原子位点上无序分布。阴离子具有3对称性。在晶体中，阳离子和阴离子之间的氢键形成平行于(001)的复杂层。这些层由垂直于前者的氢键补充，形成三维网络。
