STRUCTURE OF ZINC TETRAPHENYLPORPHYRIN DIMETHYL FORMAMIDE METHYLENE-CHLORIDE

C48H37N5ZnOCl2, M(r) = 836.13, triclinic, P1BAR, a = 11.2231(15), b = 12.5155(18), c = 14.6013(19)angstrom, alpha, = 99.001(7), beta = 94.60 0(8), gamma = 103.221(7)degrees, V = 1957.6(5) angstrom3, Z = 2, D(x) = 1.419 gcm-3, MoKalpha (lambda = 0.7107 angstrom), mu(calc) = 13.4 cm -1, F(000) = 1670, T = 173 +/- 1K, final discrepancy factor 2.8 % for 5274 unique reflections above 2.5 sigma(I) in the range 3 < 2theta < 4 8-degrees. The metal is coordinated to the four nitrogen atoms of the porphyrin ring and the oxygen of the dimethyl formamide moiety. The ge ometry of this porphyrin is nonplanar with respect to the overall stru cture, although the pyrrole rings are nearly coplanar with the zinc me tal pulled out of the plane in the familiar domed-shaped geometry.
