摘要：

The preparation and characterization of the bis(1-methylimidazole)(meso-tetraphenylporphinato)iron(III) perchlorate complex is described. The molecular structure has been determined by an X-ray crystal structure determination. The complex has two axial imidazole ligands that are nearly coplanar and close to eclipsing an Fe-N(p) bond. A rhombic distortion in the equatorial bonds is seen; the set that is approximately perpendicular to the imidazole ligand planes has an average value of 1.973(6) angstrom while the other set has an average value of 1.991(4) angstrom. The axial Fe-N(Im) bond distances average to 1.974 angstrom. The complex has a rhombic EPR spectrum and the derived crystal field parameters are reported. Crystal data: a = 10.730(1), b = 21.207(4), c = 21.231(4) angstrom, and beta = 96.82(1)-degrees, monoclinic, space group P2(1)/n, V = 4796.8 angstrom-3, Z = 4, R1 = 0.066, R2 = 0.074 based on 6429 observed data.
