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 (Equation Presented) is discussed.

Square-planar configuration of the chelate entity of dinuclear Cu(II) chelate compounds obtained from tridentate hydrazonimines was established by electronic spectroscopy, molecular-weight measurements, and proton magnetic resonance.The introduction of various substituents into the γ position of the quasiaromatic metallocycle and into the para position of the phenyl ring of the hydrazone fragment has no substantial effect on the structure of the chelates.
