Tetranuclear Copper(II) Complex with N,N′-bis(2-N-Tosylaminobenzylidene)-1,3-Diaminopropan-2-ol: Crystal structure and magnetic properties

Abstract

Tetranuclear copper(II) complex, [Cu4L2(OOCCH2COO)], where L is triply deprotonated bis-N,N′-(2-N-tosylaminobenzylidene)-1,3-diaminopropan-2-ol, in which two binuclear fragments are linked by the malonate dianion, is synthesized. The exchange interaction in the binuclear clusters is shown to be antiferromagnetic (2J = −59 cm−1), whereas the intercluster interaction is ferromagnetic (zJ’ = 7.5 cm−1). The structure of the DMSO solvate of the complex is determined by X-ray diffraction analysis.
