Complexes [Zn( bpdc)(H2O)(2)] (1) and [Mn(bpdc)(H2O)(3)]center dot 2.5H(2)O (2) were assembled by 2,2'-bipyridine-6,6'-dicarboxylate (H(2)bpdc) with Zn2+ or Mn2+ under hydro/solvo-thermal conditions. Complexes 1 and 2 are extended from mononuclear to 1D, 2D and 3D supramolecular network step by step with the help of intramolecular weak interactions. The luminescent properties of 1 had been investigated in details, which show intense blue emission with relatively good quantum yield. The 2 displays nonlinear optical (NLO) activity comparable with that of KDP, and exhibits weak antiferromagnetic coupling between the Mn (II) ions by the hydrogen bonds. (C) 2012 Elsevier B.V.
