Abstract

Full title: Mononuclear and binuclear copper(II) complexes of benzene-1,2-dioxyacetic acid (bdoaH₂) : X-ray crystal structures of [Cu(bdoa)(C₆H₅NH₂)₂]₂C₆H₅NH₂ and [Cu₂(bdoa)(bipy)₄] bdoa·8.66H₂O ((C₆H₅NH₂ = ANILINE, bipy = 2,2′-bipyridine). The copper(II) complex [Cu(bdoa)(H₂O)₂] (1; bdoaH₂ = benzene-1,2-dioxyacetic acid) reacts with aniline in an ethanol-water mixture to give [Cu(bdoa) (C₆H₅NH₂)₂]₂ C₆H₅NH₂ (2). The X-ray crystal structure of 2 shows the asymmetric unit to contain two mononuclear [Cu(bdoa)(C₆H₅NH₂)₂] units and a solvate aniline molecule. Each copper(II) atom has essentially square planar coordination and is bonded to the nitrogen atoms of two trans aniline molecules and a single oxygen atom from each of the two carboxylate moieties of the bdoa^2- ligand. The ether oxygen atoms of the bdoa^2- bond only weakly to the metal, and one of the metals also interacts weakly with the solvate aniline. Compound 1 reacts with 2,2′-bipyridine (bipy) to form the binuclear copper(II) complex [Cu₂(bdoa)(bipy)₄]bdoa·8.66H₂O (3). The X-ray crystal structure of 3 shows a discrete [Cu₂(bdoa)(bipy)₄]²⁺ dication, an uncomplexed bdoa^2- dianion and water molecules linked by OH...O hydrogen bonding. The dication has two-fold crystallographic symmetry, and the coordination of the unique copper atom is N₄O₂ distorted octahedral. Only one of the carboxylate oxygens is strongly bonded and the other forms a weak interaction with the metal. Spectral, magnetic, conductivity, voltammetry and thermogravimetric data for the complexes are given.
