Structure and Properties of the Condensation Product of 2-Oxo-1,2-dihydroquinoline-3-carbaldehyde with Stearic Acid Hydrazide and Its Complexes with Cu(II) and Ni(II)

The complex formation properties of the product 2-oxo-1,2-dihydroquinoline-3-carbaldehyde condensation with stearic acid hydrazide towards Cu(II) and Ni(II) ions has been studied. Composition and structure of the complexes has been found dependent on the nature of the metal and acid residue. The obtained compounds have been investigated by spectral methods, the temperature dependence of the magnetic susceptibility in constant magnetic field has been measured. Quantum-chemical simulation of possible isomers of N ’-acylhydrazone in a solution has been carried out.
