Abstract

In the title mononuclear complex, [Cu(C8H7O2)Cl(C12H8N2)(H2O)], the CuII atom is coordinated by one carboxylate O atom from a monodentate 4-methyl­benzoate ligand, two N atoms from the 1,10-phenanthroline ligand, one chloride ion and one water mol­ecule in a square-pyramidal geometry. The crystal structure exhibits inter- and intra­molecular C—H⋯Cl, C—H⋯O, O—H⋯Cl and O—H⋯O hydrogen bonds, as well as C—H⋯π inter­actions of phenanthroline and methyl H atoms towards the π-systems of neighboring 4-methyl­benzoate units and the pyridine rings of the phenanthroline system [centroid–centroid distances are 2.706 (2) and 2.992 (1) Å, respectively].

Highlights

  • In the title mononuclear complex, [Cu(C8H7O2)Cl(C12H8N2)(H2O)], the CuII atom is coordinated by one carboxylate O atom from a monodentate 4-methylbenzoate ligand, two N atoms from the 1,10-phenanthroline ligand, one chloride ion and one water molecule in a square-pyramidal geometry

  • H atoms treated by a mixture of independent and constrained refinement max = 0.36 e Å3

  • We report the crystal structure of the title compound, (I), a new Cu complex obtained by the reaction of 4-methylbenzoic acid, 1,10phenanthroline and copper chloride in an alkaline aqueous solution
