Crystal structure of Bis(tri-2-pyridylamine)iron(II) diperchlorate

Abstract

The crystal structure of the title compound, [Fe((C₅H₄N)₃N)₂] (ClO₄)₂, has been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to a residual of 0.059 (1995 'observed' reflections). Crystals are monoclinic, P2₁/a, a 12.815(4), b 17.503(7), c 8.318(3) Ǻ, β 121.38(3)°, Z 2. The complex cation lies with the metal atom on a centre of symmetry, the metal being six-coordinate, so that only one of the tridentate ligands is crystallographically independent. The geometry about the metal atom deviates only trivially from octahedral, <N-Fe-N> within the one ligand being 88.1°. <Fe-N> is 1.98₂ Ǻ.
