The compounds [Cu 3 Cl 3 (bipypy)] ( 1 ), [CuBr(bipypy)] 2 ( 2 ), [Cu 2 Br 2 (bipypy)] ( 3 ), and [Cu 3 (CN) 3 (bipypy)] ( 4 ) were prepared from mixtures of the copper halide salts and the ligand bis-2,3-(2-pyridyl)pyrazine (bipypy) in hydrothermal media. The series of compounds includes molecular, one- and two-dimensional species and demonstrates a trend in increasing complexity. The synthetic conditions, methods of structural characterization and descriptions of the structures of compounds 1 − 4 are presented.
