Bis(1-methyl­imidazole)[meso-α,α,α,α-tetra­kis(o-nicotinamido­phen­yl)porphinato]iron(II)–1-methyl­imidazole–tetra­hydro­furan (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-methyl­imidazole ligands in the axial sites. One 1-methyl­imidazole and one and a half tetra­hydro­furan solvent mol­ecules 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 Å). The average Fe—N(p) (N(p) refers to the pyrrole nitro­gen atoms in the porphyrin) bond length is 1.990 (9) Å, and the axial Fe—N(Im) (N(Im) refers to the imidazole nitro­gen atoms) bond lengths are 1.993 (3) and 2.004 (3) Å. The dihedral angle between the two coordinated 1-methyl­imidazole planes is 56.6 (2)°. The dihedral angles between the 1-methyl­imidazole 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 inter­actions are observed in the crystal structure.
