Synthesis and crystal structure of 5,10,15,20-tetrakis(3,5-dinitrophenyl)porphyrin

The synthesis, characterization and crystal structure of the octanitro-subs tituted porphyrin 5,10,15,20-tetrakis(3,5-dinitrophenyl)porphyrin H2T(3,5-D NP)P, are described. The solid state structure has two porphyrins in the un it cell with eight pyridine solvates and is made up from columnar arrays of the porphyrins. X-ray crystal structure data: monoclinic, space group P1 2 (1)/n1, a = 14.9996(9) Angstrom, b = 8.2489(5) Angstrom, c = 24.818(2) Angs trom, alpha = 90 degrees, beta = 104.172(1)degrees, gamma = 90 degrees, V = 2977.3(3) Angstrom(3), d(calc) = 1.440 g m(-3), Z = 2.
