Vv. Lukov et al., Structure and magnetic characteristics of new binuclear complexes based onbisbenzoylhydrazones of 2,6-diformyl-4-R-phenols and copper(II) nitrate, RUSS J C CH, 27(2), 2001, pp. 135-137
A series of binuclear Cu(II) complexes with bisbenzoylhydrazones of 2,6-dif
ormyl-4-R-phenols (R = OCH3, CH3, CH2Ph, Cl, Br, CO2CH3) with H2LCu2(NO3)(2
)(OCH3) composition, where H2L- are monodeprotonated bishydrazones, was syn
thesized. The structure of the obtained complexes was established using IR
spectroscopy and conductometric and magnetochemical data. The title complex
es were shown to exhibit exchange interaction of the antiferromagnetic type
. Results of quantum-chemical calculations of structures modeling the state
of a ligand in the complex were used to discuss the effect of substituent
R nature on magnetic exchange in the complexes.
