Tris(2,2′-bipyridine)iron(II) tris(dicyanomethylidene)methanediide

The asymmetric unit of the title compound, [Fe(C10H8N2)3][C{C(CN)2}3], contains an iron–bipyridyl unit and one third of two crystallographic independent tris(dicyanomethylidene)methanediide units. As a result of crystallographic site symmetry the ratio of cations to anions is 1:1. The tris(2,2′-bipy...

Description
Summary:The asymmetric unit of the title compound, [Fe(C10H8N2)3][C{C(CN)2}3], contains an iron–bipyridyl unit and one third of two crystallographic independent tris(dicyanomethylidene)methanediide units. As a result of crystallographic site symmetry the ratio of cations to anions is 1:1. The tris(2,2′-bipyridine)iron(II) cation has threefold symmetry. The two crystallographic independent tris(dicyanomethylidene)methanediide 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.
