Crystal and Molecular Structure of the Discogen bis[1,3-di(p−n−octyloxy-phenyl)propane-1,3-dionato]copper(II)

Abstract

The transition metal containing discogenic bis[1,3-di(p−n−octyloxy phenyl)propane-1,3-di-onato]copper(II) crystallizes in the triclinic space group P1 with two molecules in a unit cell of dimensions a = 11.300(9), b = 16.101(1), c = 17.089(2)Å, α = 82.23(1), β = 74.88(4), γ = 77.43(3)°. The crystal structure was solved by direct methods and refined to R = 0.097 by the structure factor least squares procedure. The copper atom is surrounded by four oxygen atoms in a square planar arrangement. The octyloxy chains are fully extended. The crystal structure has both layer-like and columnar characteristics. The repeating unit along the column is a molecular pair. The copper atoms are distributed about the column axis in a zig-zag fashion.
