Abstract

The binuclear copper(II) complex [Cu2(L)(Mp)(H2O)((CH3)2SO)] (Mp is 6-methoxypurinate anion) with the heterocyclic azomethine ligand, which is the condensation product of 1,3-diaminopropan-2-ol and 4-hydroxy-3-formylcoumarin (H3L), is synthesized and structurally characterized (CIF file CCDC no. 982199). The temperature dependence of the magnetic susceptibility is measured and shows a significant exchange interaction of the antiferromagnetic type (2J = −348 cm−1) in the compound. This sharply distinguishes the new complex from the earlier studied compounds with a similar exchange fragment characteristic of the ferromagnetic exchange. The antiferromagnetic exchange parameter is calculated by the quantum-chemical DFT method in the broken symmetry approximation.
