CRYSTAL STRUCTURE AND MAGNETIC PROPERTIES OF A NEW OXO-CENTRED BASIC BENZOATE BRIDGING HETEROTRINUCLEAR COMPOUND [CR2MNO(PHCOO)(6)PY(3)][CRO3CL]

摘要

A new oxo centred heterotrinuclear complex [Cr2MnO(PhCOO)(6)Py(3)][CrO3Cl] was synthesized, which exhibited weak antiferromagnetic interaction between three atoms Cr-III, Cr-III and Mn-III. The J values for Cr-III-Mn-III and Cr-III-Cr-III have been estimated; the central O atom provides the main superexchange pathway. It indicated that the distance of M-(mu(3)-O) is an important factor for metal-metal superexchange interaction. Copyright (C) 1997 Elsevier Science Ltd. [References: 20]
