The goal of this study was to develop a self-assembly synthetic strategy for the preparation of coordination polymers using the tetrazolate ligand 5-(4-pyridyl)tetrazole (4-Hptz). The synthetic method, the structures of the products were investigated.
The reaction of Cu(CH3COO)2•H2O with 4-Hptz and H3PO4(aq) under hydrothermal conditions produced a 2D coordination polymer {[Cu(4-ptz)2(H2O)2]}n (1). The reaction of Cu(NO3)2•3H2O with 4-H-ptz and 1,5-naphtalenedisulfonate (1,5-Na2nds) under hydrothermal conditions afforded a 2D coordination polymer {[Cu(OH)(1,5nds)0.5(4-ptz)]•H3O}n (2), a 3D coordination polymer {[Cu3(OH)(1,5nds) (4-ptz)3(H2O)4]•toluene}n (3), and a 1D coordination polymer {[Cu(1,5nds)(4-ptz)2 (H2O)2] •2H3O•2H2O}n (4). The reaction of CuCl2•2H2O with 4-Hptz and sodium 3,5-dicarboxybenzenesulfonate (NaH2sip) under hydrothermal conditions afforded a monomeric molecule {[Cu2(NaHsip)2(4-ptz)2(H2O)4]•2H2O}n (5), and reaction of Cu(NO3)2•3H2O under water bath conditions resulted in the formation of a 3D coordination polymer {[Cu3(OH)3(4-ptz)3(H2O)4]•4H2O}n (6).
The structures of the six coordination polymers were characterized by IR spectroscopy, elemental analysis and single-crystal or powder X-ray diffraction methods. The thermal stability and photophysical properties of the products were evaluated by TGA and solid state emission spectroscopy.
