Bis(1H-imidazole-κN){2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato-κO,N,N',O'}iron(III) perchlorate

The title compound, [Fe(C(17)H(16)N(2)O(2))(C(3)H(4)N(2))(2)]ClO(4), consists of monomeric [Fe(salmen)(HIm)(2)](+) cations {salmen is the 2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphen-olate dianion and HIm is 1H-imiazole} and perchlorate anions. In the cation, the Fe(3+) ion is octahedrally coordinated by two N atoms and two O atoms from a tetra-dentate salmen anion and two N atoms from two Him mol-ecules. These ligands are coordinated to the iron ion in a direction perpendicular to the [Fe(salmen)](+) coordination plane. The benzene ring planes in the salmen ligands are oriented nearly parallel to one another inter-molecularly [dihedral angle = 6.36 (3)°]. The dihedral angle between the mean planes through the imidazole rings in the cation is 76.9 (2)°. In the crystal, N-H⋯O inter-actions link the mol-ecules into a one-dimensional double chain running along [101] and C-H⋯O inter-actions link the double chains into a two-dimensional network, running parallel to the ac plane.
