Reactions of Hpymtza (Hpymtza = 5-(2-pyrimidyl)tetrazole-2-acetic acid) with MCl2(M = Mg(II), Sr(II), Ba(II)), produced three new coordination compounds, [Mg(H2O)6]·2pymtza·H2O (1), [Sr(pymtza)2(H2O)2]·4H2O (2), [Ba(pymtza)2(H2O)4]·H2O (3), These compounds were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Compound 1 shows a mononuclear structure while 2 and 3 reveal 1-D structures via bridging pymtza as linker. Furthermore, the luminescent properties of 1-3 were investigated at room temperature in the solid state.

Four new coordination compounds, namely mononuclear [Zn(pyrtza) 2(H2O)2] (1), binuclear [Ni(pyrtza)(H 2O)2Cl]2 (2), 1D [Cd(pyrtza)2] (3), and 2D [Mn(pyrtza)Cl] (4), were synthesized by the reactions of Hpyrtza (Hpyrtza = 5-(2-pyrimidyl) tetrazole-2-acetic acid) with MCl2 (M = Zn(II), Ni(II), Cd(II), Mn(II)) in the presence of KOH under solvothermal conditions. The compounds were characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. The luminescence properties of the complexes were investigated at room temperature in the solid state. Graphical Abstract: Four new coordination compounds, namely mononuclear [Zn(pyrtza) 2(H2O)2] (1), binuclear [Ni(pyrtza) (H 2O)2Cl]2 (2), 1D [Cd(pyrtza)2] (3), and 2D [Mn(pyrtza)Cl] (4), were synthesized [Hpyrtza = 5-(2-pyrimidyl) tetrazole-2-acetic acid].

Reactions of Hpymtza [Hpymtza = 5-(2-pyrimidyl)tetrazole-1-acetic acid] with MnCl2·4H2O under different pH conditions, afforded the complexes [Mn(pymtza)2(H2O)4] (1) and [Mn2(pymtza)2Cl2(EtOH)]·H2O (2). The compounds were structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Compound 1 shows a mononuclear structure, whereas complex 2 has a 1D chain structure. In compound 1, the pymtza ligand only acts in a monodentate manner to coordinate to one central MnII atom by one carboxylate atom, In 2, pymtza acts as tetradentate ligand to connect three MnII ions. Compounds 1 and 2 display 3D networks by hydrogen bonding interactions. Furthermore, the luminescence properties of Hpymtza as well as compounds 1 and 2 were investigated at room temperature in the solid state.

A newly developed nonionic amphiphile (GPGS-1500), a diester composed of a Guerbet alcohol (2-octyldodecan-1-ol), poly(ethylene glycol) 1500 (PEG 1500), and succinic acid esters, has been prepared as an effective nanomicelle-forming species for the synthesis of tetrazoles in water at room temperature. We have designed a new nonionic amphiphile (GPGS-1500) for the synthesis of tetrazoles in water at room temperature. The reaction conditions were optimized, and the size of the micelles formed by GPGS-1500 in water was measured by dynamic light scattering. Copyright

Eleven chelating tetrazole-containing ligands have been synthesized, and their complexes with palladium(II) and ruthenium(II) prepared.Proton n.m.r. spectroscopy, electronic absorption spectroscopy and cyclic voltammetry have been used to study the nature of the metal-ligand interactions in these complexes.The negatively charged tetrazolate group is shown to be a strong electron donor with very different properties to those of the protonated or alkylated tetrazole group.This leads to pH control of the properties of transition metal complexes containing such ligands.
