Bis[tris(pyridin-2-yl)amine]iron(II) tris(dicyanomethylidene)methanediide

Abstract

In the title compound, [Fe{(C5H4N)3N}2][C{C(CN)2}3], both ions lie across centres of inversion, with the anion being statistically disordered over two sets of atomic sites having equal occupancy. The cation and anion have approximate \overline{3} and 32 symmetry, respectively, and the Fe—N bond lengths indicate low-spin FeII. A combination of two-centre C—H...N and three-centre C—H...(N)2 hydrogen bonds link the ions into complex sheets. Several low-occupancy water molecules are present, whose H atoms could not be located: accordingly, the reflection data were subjected to the SQUEEZE procedure [Spek (2015). Acta Cryst. C71, 9–18].
