Crystal and molecular structure of 10-(4′-N-pyridyl)-5,15,20-triphenylporphinato indium(III) chloride

A study of the metallation of meso 10-(4′-N-pyridyl)-5,15,20-triphenylporphyrin with indium is reported. The crystal structure of the title compound has been determined by single-crystal X-ray diffraction. The complex crystallizes in the space group P 2 1 / n with Z = 4 and a = 10.146(2), b = 16.096(4), c = 20.861(2) A, β = 90.33 (1)° and V = 3407 A 3 . The crystal structure was refined to a conventional r (F) = 0.059 for 6355 out of 8613 reflections having δ( I )/I < 0.5. The indium-chlorine distance is 2.374(2) A, whereas the indium atom lies 0.608 and 0.7214 A from the plane of the four porphyrin nitrogens and the 24-atom porphyrin plane, respectively. The four outer-sphere aromatic subs…
