Three new coordination polymers [Zn(Htip)Cl(H2O)](n) (1), [Zn(Htip)(2)](n) (2) and [Cd(Htip)(2)](n)center dot 2nH(2)O (3) were synthesized by reactions of Zn(II)/Cd(II) salts with a multidentate tetrazole-based ligand 2(4-(tetrazol-5-yl) phenyl)imidazo(4,5-f)(1,10)phenanthroline (H(2)tip). Complex 1 possesses an infinite 1D coordination chain, and further forms the final 3D supramolecule through pi center dot center dot center dot pi stacking interactions. Complexes 2 and 3 are isomorphous, and both of them feature an 8-fold interpenetrating 4-connected 3D framework with the dia topological net and the Schlafli symbol of {6(6)}. In 1-3, the Htip(-) ligand links two metal centers through three terminal N-donors. The structural analyses indicate that the anions and solvents can subtly influence the formation of the resulting network. Moreover, the thermal stabilities and photoluminescent properties of 1-3 are investigated in the solid state. (C) 2015 Elsevier B.V. All rights reserved.
