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

摘 要: | Crystal structure of 1, 4, 8, 11, 15, 18, 22, 25-octa-butoxyphthalocyaninato- copper (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.

Abstract: | 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 monoclinic, 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. |
