Polynuclear Co(II) and Cu(II) complexes of tetraacetylethane: CuII2(dpa)2(tae)(O2CCF3)2, {[CuII2(dpa)2(tae)(4,4'-bipy)](O2CCF3)2}n, and [CoII2(dpa)4(tae)](O2CCH3)2(H2O)2, dpa = 2,2'-dipyridylamine, tae = tetraacetylethane dianion

The syntheses and structures of copper(II) and cobalt(II) complexes employing tetraacetylethane as the bridging ligand have been investigated. The reaction of Cu(O 2 CCF 3 ) 2 with tetraacetylethane (tae) and 2,2'-dipyridylamine (dpa) yielded a dinuclear complex Cu II 2 (dpa) 2 (tae)(O 2 CCF 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 …
