“…The H 3 tda ligand (1H-1,2,3-triazole-4,5-dicarboxylic acid) can be partially or fully deprotonated acting in different coordination modes [9,13,18] when coordinating to 1H-1,2,3-Triazole-4,5-dicarboxylic acid 2991 metal ions under different conditions; two coordination modes have been observed in 1 and 2 ( figure 9). In 1, H 3 tda is fully deprotonated to tda 3À and adopt hexadentate coordination mode chelating three Zn(II) ions, while in 2 Htda 2À adopt tridentate coordination mode connecting two Co(II) ions.…”

Zn 3 (tda) 2 (bipy) 2 (H 2 O) 2 Á 4H 2 O] n (1) and [Co 2 (Htda) 2 (H 2 O) 6 Á5H 2 O] (2) have been synthesized and characterized structurally by X-ray diffraction, where H 3 tda ¼ 1H-1,2,3-triazole-4, 5-dicarboxylic acid and 2,2 0 -bipy ¼ 2,2 0 -bipyridine. Their solid-state structures have been characterized by elemental analysis and IR spectroscopy. The molecular unit of 1 consists of two crystallographically unique Zn(II) ions assuming different coordination geometries, the tda 3À exhibits a hexadentate binding mode chelating three Zn(II) ions; neighboring Zn-Zn distances through tda 3À bridges are 5.910(6), 5.888(5), and 6.279(3) Å , respectively. In 2, two neighboring Co(II) ions are bridged by two Htda 2À ligands, forming a binuclear structure, with Co-Co distance of 4.091 Å and is further linked to generate a 3-D structure via hydrogen bonds. Fluorescent of 1 was investigated.

“…The corresponding axial position is taken by two oxygen atoms (O9 and O10) from two water molecules with an O9-K1-O10 angle of 157.97 (5) In that complex, every HTDA 2-ligand links two Gd(III) ions to form a 1-D zigzag chain [14]. The chains are linked by intermolecular hydrogen bonds between the nitrogen atoms in the triazole ring and the oxygen atoms of the carboxylate groups to form 2-D layers.…”

4 (3) have been synthesized and characterized structurally by X-ray diffraction, where H 3 TDA ¼ 1,2,3-triazole-4,5-dicarboxylic acid and phen ¼ 1, 10-phenanthroline. Their solid-state structures have been characterized by elemental analysis and IR spectroscopy. In 1, a 3-D (4, 8)-connected metal-organic framework has been constructed using dinuclear potassium clusters as eight-connected nodes and the ligands as four-connected nodes; it represents the fluorite topology network. Compound 2 exhibits 1-D chains along c-axis, which are connected by strong hydrogen-bond interactions in 2-D layers; the layers are further stacked via hydrogen bonds in the b-direction. In 3, two neighboring Mn(II) ions are bridged by two 1,2,3-triazole-4,5-dicarboxylic groups, forming a binuclear structure, with Mn(II) Á Á Á Mn(II) distance of 4.356 Å , which is further linked to generate a 2-D layer structure via interdimer hydrogen bonds. The fluorescence for these compounds was investigated.

“…1H-1,2,3-triazole-4,5-dicarboxylic acid (H 3 TDA) is a multidentate N-and O-donor ligand that can be deprotonated to generate H 2 TDA  , HTDA 2 , and TDA 3 with versatile metal-binding and hydrogen-bonding capabilities. Complexes of the H 3 TDA ligand have been reported with alkali metal ions, transition metal ions and lanthanide metal ions [14][15][16][17][18][19][20][21]. As a continuation of our ongoing interest in the construction of novel coordination polymers with interesting structural features, we report herein the syntheses and crystal structures of two novel coordination polymers [Pb(HTDA)] n (1) and [Co 5 (TDA) 2 (H 2 TDA) 2 (H 2 O) 8 ] n (2).…”

Two novel three-dimensional (3-D) coordination polymers, [Pb(HTDA)] n (1) and [Co 5 (TDA) 2 (H 2 TDA) 2 (H 2 O) 8 ] n (2) [H 3 TDA = 1H-1,2,3-triazole-4,5-dicarboxylic acid], have been prepared by hydrothermal reactions and characterized by elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction. Compound 1 is constructed from rod-shaped secondary building units (SBUs) and exhibits a 3-D network with (4 10 ·6 5 )(4 10 ·6 3 ·8 2 ) topology. Compound 2 is built up from ligands bridging three different cobalt ions and exhibits a 3-D network with (4·8 2 ) 3 (4·8 2 ·10 3 ) topology. In addition, the thermal stabilities of the two compounds, the photoluminescence properties of compound 1 and the magnetic properties of compound 2 have been studied. coordination polymer, hydrothermal reaction, 1H-1,2,3-triazole-4,5-dicarboxylic acid, secondary building units, transition metal
