title: Structure of (2,3,7,8,12,13,17,18-octaethylporphinato)dioxoosmium(VI).
abstract: [Os(C36H44N4)O2].C6H5Cl, Mr = 867.53, triclinic, P1, a = 8.177 (1), b = 10.668 (1), c = 11.791 (1) A, a = 73.91 (1), beta = 83.18 (1), gamma = 75.07 (1) degree, V = 953.6 A3, Z = 1, Dx = 1.51 g cm-3, Dm = 1.50 g cm-3, Mo K alpha, lambda = 0.71073 A, mu = 34.5 cm-1, F(000) = 438, T = 293 K, R = 0.048 for 5721 unique observed reflections. The Os atom is centered in the porphinato plane with an average Os-N = 2.052 (6) A and Os-O = 1.745 (5) A. The 24-atom porphyrin core is effectively planar with the largest deviation from the mean plane less than 0.02 A.
