Abstract

The composition of the coordination polyhedron of the complex of copper(II) acetate with 2-[2-hydroxyphenyl]-4,4-diphenyl-1,2-dihydro-4H-3,1-benzoxazine in the solid state and solutions of ethanol and chloroform is studied. Using the angular overlap model, the interaction energy of the copper(II) ion with donor atoms of the ligand is calculated. The temperature dependence of the molar magnetic susceptibility (χМ) of the complex in the solid state is studied; the occurrence of the exchange interaction of the antiferromagnetic type between two copper ions is found (2J = -57.8 cm-1).
