摘要:
The binuclear complexes of Cu2+ and Ni2+ with a new ligand system obtained through condensation of amino alcohols with 2-phenylhydrazone 1-phenylbutane-1,2,3-trione were synthesized. The compositions and structures of ligands and complexes were determined using elemental analysis, IR and NMR spectroscopy and magnetochemistry. The nickel complexes were found to be diamagnetic; in the copper complexes, substantial antiferromagnetic exchange interaction was observed (for Cu2+ complexes with n = 2 and 3, 2J is equal to -396 and -393 cm(-1), respectively). The structure of the exchange fragment[GRAPHICS]is discussed.
