Abstract

A new complex of copper (II) with 3-(2-hydroxy-3-sulfo-5-nitrophenylazo)-pentadione-2,4 (HL) is synthesized and analyzed by single crystal XRD. The crystals are monoclinic: a = 7.7563(4) Å, b = 24.0157(12) Å, c = 24.6353(13) Å, β = 91.9490(10)°, V = 4586.2(4) Å³, space group P2₁/c, Z = 2, ρ_calc = 1.713 g/cm³, R = 0.0695. The environment of the copper atom is formed by three oxygen atoms, the nitrogen atom of tetradentate ligand, and the oxygen atom of a water molecule.
