Abstract
Two new copper complexes [Cu(Hdpa)(en)] (1) and [{Cu(μ-na)(CHOH)}·2CHOH] (2) (where en is ethylene diamine, Hdpa is 2′-carboxy-[1,10-biphenyl]-2-carboxylate anion and na is 1-naphtalenecarboxylate) have been synthesized and their crystal structures were determined by X-ray crystallography. Complex 1 was prepared from the reaction of Cu(NO)·3HO with ethylene diamine and 2,2′-biphenyldicarboxylic acid in a mixture of water and methanol and complex 2 was prepared from the reaction of CuSO·5HO with 1-naphtalenecarboxylic acid in methanol. The two complexes were characterized by IR, UV-vis, luminescence and elemental analysis. Moreover, complex 2 was characterized by EPR spectroscopy and thermogravimetric analysis. Complex 1 is a monomer and complex 2 is a dimer with a paddle- wheel structure; both structures are without precedent in the literature. [ABSTRACT FROM AUTHOR]
