The straightforward and facile synthetic approaches towards four coordination polymers, {[CdL(H2O)]·0.5H2O}n, {[Cd2L2(H2O)2(4,4′-bipy)]·4H2O}n, {[Cd2L2(H2O)2(4,4′-azpy)]·3H2O}n and {[CoL(H2O)3]·2.5H2O}n (4,4′-bipy = 4,4′-bipyridine; 4,4′-azpy = 4,4′-azopyridine), based on the polydentate ligand 1-(4-carboxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylic acid (LH2) and Cd(II) and Co(II) ions are reported. In addition, two mononuclear complexes, [Cu(HL)2(DMA)] and [Cu(HL)2(H2O)2], derived from the same ligand and the Cu(II) ion have been prepared. The coordination compounds have been characterized by infrared spectroscopy, thermogravimetry, powder X-ray diffraction and elemental analysis. Single crystal X-ray structures for each of these coordination compounds have been established. The specific surface of the 3D Cd(II)- and Co(II)-derived coordination polymers, determined through nitrogen adsorption, is negligible (SBET < 25 m2/g). |
