Three coordination polymers, namely, [Zn-2(ndd)(2)(2,2'-bpy)(2)center dot 2H(2)O](n) (1) [Cd(ndd)(2,2'-bpy)](n) (2), and [Cd(ndd)(1,4-pyb)](n) (3), where H(2)ndd = 2,2'-(naphthalene-1,5-diylbis(oxy))diacetic acid, 1,4-pyb = 1,4-bis(pyridin-4-ylmethoxy)benzene and 2,2'-bpy = 2,2'-bipyridine, have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction analyses, powder X-ray diffraction and thermogravimetric analysis. Compound 1 can be considered as a 1D chain, which is further linked through the strongly multiple pi-pi interactions into a 3D supramolecular structure. By changing the metal ions, compound 2 is the 2D square structure (10.96 x 15.20 angstrom) with the 4(4).6(2) topology. By changing the auxiliary ligand, compound 3 presents a new (4,5)-connected 3D network with the point symbol of (4(2).6(5).8(3))(2).(6(6)). Furthermore, compounds 1-3 show good fluorescence properties in the solid state at room temperature. Crown Copyright (C) 2012 Published by Elsevier B. V. All rights reserved.
