Abstract A new 2D 5-connected coordinationpolymer [Zn3(HL2)(1,4-bdc)3] (1) (HL2 = 3,4-bis(pyridin-4-ylmethoxy)benzoicacid, 1,4-H2bdc = 1,4-benzenedicarboxylate) has been hydrothermally constructed using HL2, 1,4-bdc ligands as linear linkers and Zn3-clusters as 5-connected nodes. In addition, powder X-ray diffraction, photoluminescent property and thermogravimetric analysis for 1 are investigated

To investigate the influence of spatial extended direction on the resulting structure, three new compounds have been synthesized by the reactions of Zn-II or Cd-II salts and 3,5-bis(pyridin-4-ylmethoxy)benzoic acid (HL1) or 3,4-bis(pyridin-4-ylmethoxy)benzoic acid (HL2) with two rationally selected multicarboxylate ligands. Without a secondary ligand, an 1D ribbon structure [Zn(L-1)(2)]center dot H2O (1) furnished, the hydrogen bonds extended the structure to a 2D layer. Employing 4,4'-biphenyldicarboxylic acid (H(2)bpdc), a 2D layer structure [Zn(L-1)(bpdc)(0.5)] (2) resulted. The use of 1,3,5-benzenetricarboxylic acid (H(3)btc) led to a 3D compound [Cd-2(L-2)(btc)(H2O)] (3). It can be observed from the architectures of 1-3 that secondary ligands had great effects on the spatial connective fashions, resulting in the formation of various dimensional compounds.
