A Novel Metal-Organic 1D-Supramolecular Complex from the Self-Assembly of Copper(II) with 1,10-Phenanthroline and Biphthalate

Abstract

A new copper(II) complex of formula [Cu(phen)(BPT)H₂O]· 0.5H₂O (phen = 1,10-phenanthroline, BPT = biphthalate) has been synthesized under the ambient conditions and the crystal structure was determined by single crystal X-ray diffraction. The compound crystallizes in the system and belongs to space group: orthorhombic Pca2(1) with a = 11.14770(10)Å, b = 11.63650(10)Å, c = 14.03150 (10)Å, β = 90º, γ = 90º, V = 1820.17(3)ų, Z = 4, Dc = 1.587 g/cm³, Mr = 434.88, μ(moKo) = 1.239 mm^-1, F(000) = 888. The final R = 0.0450 and wR = 0.1166 for 3012 observed reflections with I > σ(I). The crystal structure analysis indicates that the copper(II) ion is five-coordinated in a square pyramidal geometry. The BPT and phen molecules are connected by copper(II) and form zigzag chain-like structure, then pack in 1D-supramolecular complex.
