Abstract The IR, the ligand field spectra and the crystal structure of the mixed-ligand compound [(aquo)2,2′-dipyridylamine(3-chloro-2,4-pentanedionato)copper(II)] nitrate, [Cu(dpyamH) Cl-acac(H2O)]NO3], are reported. The copper atom exists in a square pyramidal environment with the apical position occupied by the aqua ligand. The nitrogenous base and the β-dionato anion act as bidentate ligands forming six-membered chelate rings. In addition to the coulombic interactions with the metal centre, the planar NO 3 - group participates in specific electrostatic interactions involving the hydrogen atoms of the coordinated water molecule. The chlorine and the nitrogen atoms are also involved in hydrogen bonding. The structure of the compound was determined by single crystal X-ray diffraction analysis (triclinic, space group $$P\bar 1$$ , a = 8.718(5), b = 9.407(5), c = 13.484 (7) Å, α = 94.17(4)°, β = 105.12(5)°, γ = 119.75(5)°, Z = 2, R = 0.0332, R W = 0.0869).
