Abstract
Mononuclear compound I ([Co(Ptia)2(H2O)4] • H2O) and 1D chain compound II ([Ni4(Cptia)4(H2O)12]∞) 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) (H2Cptia), under different pH conditions by using the hydrothermal method. Their structure was characterized by single crystal X-ray diffraction (СIF 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.
