The ring-substituted phthalo-cyanines and its metal complexes:Crystal structure of 1,4,8,11,15,18,22,25-octa-butoxyphthalocyani- natocopper(Ⅱ)

Crystal structure of 1, 4, 8, 11, 15, 18, 22, 25-octa-butoxyphthalocyaninatocopper (Ⅱ) (1) was determined by X-ray diffraction methods. The crystal system is mono-clinic, space group is P21/c, Z = 4, a = 1.3741(1) nm, b = 2.6737(1) nm, c = 1.6690(1) nm, β=101.278(1)°. The steric congestion between the neighbouring butoxyl groups causes the distortion of the ring core of phthalocyanine (Pc) into a saddle shape conformation. In the crystal structure, molecules stack along a axis forming one-dimensional packing structure and there are two molecular overlap types which appear in turn with different distances between molecules, overlap area and angle.
