Abstract

Tetranuclear copper(II) complex [Cu4L2(OOC(CH2)6COO)] (I) based on bis(azomethine), condensation product of 1-phenyl-3-methyl-4-formylpyrazolone-5 with 1,3-diaminopropanol-2, is synthesized. The structure of its DMSO-adduct (Ia) is determined by X-ray diffraction analysis (CIF file CCDC 1447891). The complexes contain two binuclear fragments bonded by the µ4-1,6-hexadicarboxylate linker. The magnetic exchange interaction in complex I is antiferromagnetic (2J =–155 cm–1), whereas that in complex Ia is ferromagnetic (2J = 129 cm–1), which is due to different conformations of the metallochelate cycles.
