To investigate the influence of spatial extended direction on the resulting structure, three new compounds have been synthesized by the reactions of ZnII or CdII 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(L1)2]·H2O (1) furnished, the hydrogen bonds extended the structure to a 2D layer. Employing 4,4′-biphenyldicarboxylic acid (H2bpdc), a 2D layer structure [Zn(L1)(bpdc)0.5] (2) resulted. The use of 1,3,5-benzenetricarboxylic acid (H3btc) led to a 3D compound [Cd2(L2)(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.
