The copper(II) complex with 3-(2-hydroxy-3-sulfo-5-nitrophenylhydrazo)pentane-2,4-dione (H3L) is studied, and its crystal structure is studied by X-ray diffraction analysis. The crystals of [Cu(H2O)2]2(μ-L)2[Cu(H2O)4] (I) are triclinic (space group P \( \bar 1 \)) at 100 K, a = 7.085(3), b = 10.373(5), c = 12.265(6) Å, α = 0.842(5)°, β = 104.996(6)°, γ = 99.156(6)°, Z = 1). The C=O and NH groups of
