Abstract

<p>The title complex of a six-coordinated [5,10,15,20-tetrakis(2,4,6-trimethylphenyl)-porphyrinato-k4N]iron(III) complex with two 3,5-dimethylpyridine N-oxides, [Fe(TMP)(3,5-Me2PyNO)2]ClO4 (ClO4: perchlorate), was prepared, and characterized by a single-crystal X-ray diffraction method at 100(2)K. The title complex crystallizes in the triclinic space group P-1 with a = 15.2889(4)Å, b = 15.8587(4)Å, c = 16.2403(5)Å, α = 84.596(2)°, β = 63.769(3)°, γ = 84.162(2)°, V = 3508.49(19)Å3, Dx = 1.345 g/cm3, and Z = 2. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0628 and 0.1517, respectively, for all 16923 independent reflections. The average Fe–N and Fe–O distances are 2.041(3)Å and 2.033(3)Å. The porphyrin ring is a completely planar structure. We will determine the magnetic behaviors by SQUID and ESR measurements.</p>
