Structure of Ethanol Coordinated 1,8,15,22-Tetra- (2′,2′,4′-trimethyl-3′-pentoxy)phthalocyaninatocobalt

摘要

Crystal structure of ethanol coordinated 1,8,15,22-tetra(2′,2′,4′-trimethyl-3-pentoxy) phthalocyaninatocobalt (C64H80N8O4Co·2C2H5OH, Mr = 1176.43) was determined by X-ray diffrac- tion methods. The crystal is of monoclinic, space group P21/c with a = 16.4294(4), b = 8.0560(2), c = 24.3654(7)(A。), β = 98.3680(8)°, Z = 2, V = 3190.6(1) (A。)3, Dc = 1.225 g/cm3, F(000) = 1262, μ(MoKα) = 0.326 mm-1, the final R = 0.0865 and wR = 0.2737 for 4787 observed reflections with I ≥ 2σ(I). The bulky branched alkyloxy substituents lead to a one structural isomer and space the phthalocyanine molecules where two ethanol molecules coordinate to the cobalt atom from two sides of each molecule.
