Complex [Cu(C7H3NO5)(DMF)(H2O)] was crystallized from the reaction of Cu(CH3COO)2?H2O with 2,6-dicarboxy-4-hydroxypyridine (chelidamic acid) in DMF solution and its structure was characterized by X-ray crystallography. The crystal is of triclinic, space group P 1 with a = 7.835(2), b = 8.594(2), c = 10.309(2) ?, α = 84.16(3), β = 77.94(3), γ = 69.22(3)°, V = 634.4(2) ?3, Mr = 335.76, Z = 2, Dc = 1.758 g/cm3, λ = 0.71073 ?, μ(MoKα) = 1.756 mm?1 and F(000) = 342. The structure was refined to R = 0.0367 and wR = 0.0805 for 2191 observed reflections with I > 2σ(I). The crystal structure shows a distorted square pyramidal geometry around the copper(II) ion, which is chelated by one nitrogen atom and two oxygen atoms of the chelidamic acid, one water molecule and one DMF molecule. The title complex displays 1-D hydrogen-bonded double chains.
