Mononuclear compound I ([Co(Ptia)(2)(H2O)(4)]center dot H2O) and 1D chain compound II ([Ni-4(Cptia)(4)(H2O)(12)](infinity)) have been constructed from the new ditopic 1,2,3-trazol-based aromatic heterocyclic carboxylic ligand, 4-(4-carboxy-1H-1,2,3-triazol-1-yl) benzoic acid) (H(2)Cptia), under different pH conditions by using the hydrothermal method. Their structure was characterized by single crystal X-ray diffraction (CIF files CCDC nos. 1409531 (I) and 1409531 (II)), IR spectra, and elemental analysis. Compound I is a mononuclear compound. In II, two sets of parallel arrangement 1D chains orient in different directions. The results of their magnetic measurements display the antiferromagnetic interaction exists among the paramagnetic ions.
