SYNTHESES AND CRYSTAL STRUCTURES OF TWO ONE-DIMENSIONAL CHAIN COPPER BENZOYLACETONE COMPLEXES BRIDGED THROUGH AZOBISPYRIDINE LIGANDS

摘要

Two copper complexes [Cu(bzac)_2(4,4'-azpy)] H_2O (1) and [Cu(bzac)_2(3,3'-azpy)] (2) (bzac = benzoylacetone, 4,4'-azpy = 4,4'-azobispyridine, 3,3'-azpy = 3,3'-azobispyridine) have been synthesized and characterized. The crystal structures were determined by X-ray diffraction analysis. In crystals of Complexes 1 and 2, the copper atoms have distorted octahedral symmetry. The two compounds possess very similar one-dimensional linear chains linked through the rod-like 4,4'-azpy or 3,3'-azpy ligands.
