Abstract
The mononuclear copper(II) complex [CuL(CH3COO)], where L is monoanion of 1-phenyl-3-methyl-4-formylpyrazol-5-one 2-quinolylhydrazone has been synthesized. The weak intermolecular antiferromagnetic exchange interaction between copper(II) ions has been determined with the data of ESR spectroscopy and cryomagnetic measurements (2J = −3.25 cm−1). XRD data in combination with DFT calculations of exchange parameter within broken symmetry approach indicates that intermolecular exchange coupling is going through NH⋯O hydrogen bonds in centrosymmetric H-bonded dimers.
