Bis(1-methyl-imidazole)[meso-α,α,α,α-tetra-kis(o-nicotinamido-phen-yl)porphinato]iron(II)-1-methyl-imidazole-tetra-hydro-furan (1/1/1.5).

In the title compound, [Fe(II)(C(68)H(44)N(12)O(4))(C(4)H(6)N(2))(2)]·C(4)H(6)N(2)·1.5C(4)H(8)O, the central Fe(II) ion is coordinated by four pyrrole N atoms of the porphyrin core and two N atoms of the 1-methyl-imidazole ligands in the axial sites. One 1-methyl-imidazole and one and a half tetra-hydro-furan solvent mol-ecules are also present in the asymmetric unit. The complex exhibits a near planar porphyrin core conformation, in which the iron centre is slightly displaced towards the hindered porphyrin side (0.01†à ). The average Fe-N(p) (N(p) refers to the pyrrole nitro-gen atoms in the porphyrin) bond length is 1.990†(9)†à , and the axial Fe-N(Im) (N(Im) refers to the imidazole nitro-gen atoms) bond lengths are 1.993†(3) and 2.004†(3)†à . The dihedral angle between the two coordinated 1-methyl-imidazole planes is 56.6†(2)°. The dihedral angles between the 1-methyl-imidazole planes and the planes of the closest Fe-N(p) vector are 16.8†(2) and 39.8†(2)°. N-H⋯N and N-H⋯O inter-actions are observed in the crystal structure.
