“…Coordination compounds, a class of functional materials, are attracting increasing interest owing to not only their diverse structures but also their great potential in the field of luminescence, adsorption, and catalysis ( Aromi et al, 2011 ; Wriedt et al, 2012 ; Zou et al, 2014a ; Zou et al, 2015a ; Du et al, 2015 ; Shen et al, 2016 ; Zhang et al, 2016 ; Lin et al, 2019 ; Zou et al, 2021 ). Tetrazole carboxylates are bi-functional ligands with either flexible carboxylate groups or rigid tetrazole rings that have great potential for constructing a variety of coordination architectures.…”

Two Cu(II) compounds based on tetrazole-carboxylate ligands, [Cu(phtza)2(H2O)2]∙3H2O (1) and [Cu(atzipa)2]∙2H2O (2) (phtza = 2,2'-(5,5'-(1,3-phenylene)bis(2H-tetrazole-5,2-diyl))diacetate, atzipa = 3-(5-amino-1H-tetrazol-1-yl)isopropanoic anion), were designed and synthesized by hydrothermal reactions. The X-ray diffraction results show that the two compounds show two-dimensional (2D) layer structures. Nanoprecipitation with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG-2000) contributes to the formation of the nanoparticles (NPs) with excellent water dispersity. In vitro study indicates that the two NPs exert considerable cytotoxicity toward human hepatocellular carcinoma cells (HepG2 and Huh7) with low half-maximal inhibitory concentration (IC50). However, the cytotoxicity of such NPs is negligible in normal cells (HL-7702). The cytotoxicity of these NPs was also investigated by the flow cytometry and Calcein-AM/PI (live/dead) co-stained experiments. The results promise the great potential of these NPs for chemodynamic therapy against cancer cells.

“…Tetrazolecarboxylic acids with both flexible carboxylate group and rigid tetrazolyl ring, to the best our knowledge, have been widely investigated. However, those based on both tetrazole-carboxylate and auxiliary ligands have been the subject of limited study [11]. Inspired by these observations, we have selected 5-(2-pyrazinyl)tetrazole-2-acetic acid (Hpztza) to construct coordination compounds, whose -CH 2 -spacer between the tetrazole ring and carboxylate group may offer flexible orientations of the carboxylate arm, allowing the formation of various framework structures.…”

Two new coordination compounds, namely 1D [Mn(pztza) 2 (4,4 0 -bipy)(H 2 O) 2 ]Á2H 2 O (1) and [Co(4,4 0 -bipy) (H 2 O) 4 ]Á2pztzaÁ4H 2 O (2), were synthesized by the reactions of Hpztza [Hpztza = 5-(2-pyrazinyl)tetrazole-2-acetic acid] with 4,4 0 -bipyridine and MnCl 2 Á4H 2 O or CoCl 2 Á6H 2 O in the presence of NaOH. The two compounds were structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The X-ray analysis reveals that the two compounds form 1D chain structure via the bridging 4,4 0 -bipy. In compound 1, pztza acts as a monodentate ligand to coordinate to Mn(II) center, while in compound 2, pztza ligands are not coordinated to Co(II) centers, instead, they are connected to the 1D chain via hydrogen bonds. Furthermore, the luminescent properties were investigated at room temperature in the solid state.

Abstract. Reactions of K3-pytza [K3-pytza = 5-(3-pyridyl) tetrazole-2-acetato potassium salt] with MnCl 2 ·4H 2 O and 4,4Ј-bipy or mixed ligands with 4,4Ј-bipy (4,4Јbipy = 4,4Ј-bipyridine), produced two new coordination compounds, [Mn(3-pytza) 2 (H 2 O) 2 ]·2H 2 O (1) and [Mn(3-pytza) 2 (4,4Ј-bipy)] (2). The two compounds were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray dif-
