Crystal structure of fac-bis­[bis­(pyridin-2-yl)methan­amine]­iron(II) 1,1,3,3-tetra­cyano-2-(di­cyano­methyl­idene)propane-1,3-diide, [Fe(dipa)(2)](tcpd)

In the title compound, [Fe(C(11)H(11)N(3))(2)](C(10)N(6)), the Fe(II) cation is coordinated by two bis(pyridin-2-yl)methanamine (dipa) ligands and has crystallographic twofold symmetry. There are deviations from ideal octa­hedral geometry due to the steric requirements of the ligands. The polynitril...

description In the title compound, [Fe(C(11)H(11)N(3))(2)](C(10)N(6)), the Fe(II) cation is coordinated by two bis(pyridin-2-yl)methanamine (dipa) ligands and has crystallographic twofold symmetry. There are deviations from ideal octa­hedral geometry due to the steric requirements of the ligands. The polynitrile 1,1,3,3-tetra­cyano-2-(di­cyano­methylid­ene)propane-1,3-diide (tcpd(2−)) dianion is disordered about an inversion center and is not coordinated to the Fe atom. The anion is not planar but has a propeller shape. In the crystal, weak N—H⋯N inter­actions between the amine H atoms of the dipa ligands and two nitrile groups of the anion form an alternating chain of cations and anions related by the C-centering of the unit cell.
