Synthesis and Crystal Structure of a New 3D-Supramolecular Complex: [Cu(phen)(C2O4)(H2O)]+H2O

Abstract

A novel complex [Cu(phen)(C₂O₄)(H₂O)]·H₂O, where phen = 1,10- phenanthroline, was synthesized and characterized by IR spectra, elemental analysis and single-crystal X-ray. The crystal structure analysis shows that the copper(II) is a five-coordinated in a slightly distorted square pyramidal geometry environment. The complex forms layer structure and packs in 3D-superamolecular network through some π-π stacking interactions and intermolecular hydrogen bonds. The crystal is monoclinic, space group P2(1)/c with unit cell parameters: a = 8.359(2)Å, b = 9.646(3)Å, c = 17.384(5)Å, α = 90º, β =103.523(4)º, γ = 90º, V = 1362.8(6)ų, Z = 4, Mr = 367.8, Dc = 1.793 Mg/cm³, μ = 1.639 mm^-1, F(000) = 748, T = 273(2)K, R = 0.0482, wR = 0.1225 for 3096 reflections with I > 2σ(I).
