Syntheses, structures, and luminescent properties of zinc(II) complexes assembled with aromatic polycarboxylate and 1,3 -bis (1,2,4-triazol-1-yl) propane

摘要

Three new coordination compounds, {[Zn(btrp)(ip)]·2H2O}_n (1), {[Zn(btrp)(hip)]·2H2O}_n (2), and {[Zn_(13) (btrp)(btc)(H2O)]·H2O}_n (3) (btrp = 1,3-bis(1,2,4-triazol-l-yl)propane, H2ip = isophthalate, H2hip = 5-hy-droxy isophthalate, H3btc = benzene-1,3,5-tricarboxylic acid) have been prepared via solvothermal method and characterized by single crystal X-ray diffraction and elemental analysis. 1 possesses 2D (4. 4) net framewok. 2 is also a 2D infinite layer framework, and the resulting 2D structure is interconnected by hydrogen-bond and π...π interactions to lead to a 3D supramolecular architecture. 3 exhibits a novel 2D framework with three nonequivalent points, {5.6~2}{5~2.6}{5~4.8~2}. The fluorescence properties of 1-3 have been studied at room temperature.
