Abstract

The binuclear copper(ii) complexes with 2-hydroxyacetophenone acyldihydrazones (H4L) Cu2L·2Py were studied by ESR spectroscopy. In these complexes, the coordination polyhedra are linked via the polymethylene chain containing from one to five units. In the complexes based on acyldihydrazones of malonic, succinic, glutaric, and adipic acids, weak spin-spin exchange interactions occur between the paramagnetic centers. An increase in the length of the polymethylene chain to five units hinders exchange interactions, and the ESR spectrum of the corresponding complex has a signal typical of monomeric copper(ii) complexes.
