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

Abstract

The transition metal containing discogen bis[1,3-di(p-n-octylphenyl)propane-1,3-dionato]copper(II) crystallizes in the triclinic space group P1. The copper atom lies on an inversion centre and is surrounded by four oxygen atoms in a square planar arrangement. The octyl chains are fully extended in an alltrans conformation. The molecules form a tilted columnar arrangement, the angle of tilt between the disc normal and the column axis being 122°. The column axis coincides with the crystallographic a-axis. In the crystal structure, each column is surrounded by six others. Along the column axis, adjacent copper atoms are separated by 5.821 (3) Å.
