A polymeric cobalt compound [Co(DCNT)(H2O)](n) with novel topology:Synthesis, structure, luminescence, and magnetic property

The hydrothermal reaction of Co(NO3)(2)center dot 6H(2)O and a new designed ligand H2DCNT yields a three-dimensional polymer [Co(DCNT) (H2O)(n) (1), H2DCNT=2,4-bis(4-carboxyphenylamino)-6-diethylamino-1,3,5-triazine. In the structure of 1, each DCNT2- has three coordination sites, one nitrogen atom in the triazine ring coordinating to Co(II) and two carboxylates adopting mu(2)-bridging mode, which make the infinite Co(II) chains array uniformly and evenly toward crystallographic c-axis. Luminescent and magnetic properties of 1 were also studied. (c) 2007 Elsevier B.V. All rights reserved.
