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

In the title compound, [Fe{(C(5)H(4)N)(3)N}(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 [Image: see text] and 32 symmetry, respectively, and the Fe—N bond lengths indicate low-spin Fe(II). 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]. [Image: see text]
