Tris(2,2′-bipyridine)iron(II) tris(dicyanomethylidene)methanediide
The asymmetric unit of the title compound, [Fe(C<sub>10</sub>H<sub>8</sub>N<sub>2</sub>)<sub>3</sub>][C{C(CN)<sub>2</sub>}<sub>3</sub>], 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.
