Polynuclear Co(II) and Cu(II) complexes(1),(2) and (3) of tetraacetylethane: (see abstract)

The syntheses and structures of copper(II) and cobalt(II) complexes employing tetraacetylethane as the bridging ligand have been investigated. The reaction of Cu(O2CCF3)2 with tetraacetylethane (tae) and 2,2′-dipyridylamine (dpa) yielded a dinuclear complex Cu^II2(dpa)2(tae)(O2CCF 3)2 (1), which has an extended hydrogen-bonded chain structure in the solid state. The reaction of 4,4′-dipyridyl (4,4′-bipy) with compound 1 resulted in the formation …
