Molecular and Crystal Structures of Binuclear Copper(II)Complexes with Acylhydrazones of Benzenedicarboxylic Acids

摘要

Recently,we described three series of binuclear copper(II)complexes based on acetylhydrazones of(3-diketones(I),salicylaldehyde(II),and ali phatic-aromatic ketones(III).A specific feature of the molecular structure of com plexes I-III is the presence of a-(CH)_n-aliphatic bridge(spacer)connecting the coordination polyhedra of two tridentate copper chelates;hence,these com plexes can be classified as spacered dimers.
