Crystal and molecular structure of a five-coordinate zinc complex of meso-tetraphenyltetrabenzoprophyrin

Abstract The crystal and molecular structure of a five-coordinate zinc tetrabenzoporphyrin, (tetrahydrofuran)(meso-tetraphenyltetrabenzoporphyrin)zinc(II), [(TPTBP)Zn (THF)], has been determined. The molecule is severely non-planar and assumes a saddle shape. The average absolute displacement of Cb from the mean plane is 0.7652 A. The predominant feature of the crystal structure is layers of three saddle-shaped macrocycles stacked with infinite cylindrical channels along the crystallographic c-axes. The results of this study indicate that extension of the π-electron system of the porphyrinato core results in significant effects for both molecular and crystal structure.
