- Аннотация: A new representative of calix[4]arene-containing tetranuclear manganese complexes of [(Mn2Mn2II)-Mn-III] type with 2,2'-dipyridyl bidentate ligand coordinated in the equatorial plane of the complex (II) has been obtained. The complex is crystallized in monoclinic space group P2(1)/c (a = 14.9402(7) angstrom, b = 32.816(1) angstrom, c = 21.595(1) angstrom, beta = 106.888(4)). Its magnetic properties have been studied by the method of SQUID magnetometry. The substitution of a peripheral ligand was shown to influence substantially on the structure of the central fragment of the metal complex, and, hence, on the magnetic properties. Quantum-chemical calculations were performed for this complex and for the similar calix[4]arene-containing manganese complex with pyridine ligand (I). The influence of peripheral environment on the magnetic properties of tetranuclear manganese skeleton was elucidated for both complexes. (C) 2014 Elsevier B.V. All rights reserved.
