Crystal structure and Hirshfeld surface analysis of a new mononuclear copper(II) complex: [bis-(pyridin-2-yl-κ N )amine](formato-κ O )( m -hy-droxy-benzoato-κ 2 O , O ')copper(II).

A new mononuclear copper(II) complex, [Cu(C 7 H 5 O 3 )(HCO 2 )(C 10 H 9 N 3 )], containing mixed N - and O -donor ligands, 2,2'-di-pyridyl-amine (dpyam) and m -hy-droxy-benzoate ( m -OHbenz), has been obtained from a solvent mixture. The coordination environment of the Cu II ion is distorted square-pyramidal with a [N 2 O 3 ] coordination set originating from the chelating dpyam and m -OHbenz ligands in the basal plane and the O atom of a formato ligand at the apical position. The crystal structure of the title complex is stabilized by N-H⋯O, O-H⋯O, C-H⋯O hydrogen-bonding, π-π and C-H⋯ π inter-molecular inter-actions, which were qu-anti-fied by Hirshfeld surface analysis.
