Synthesis of Bis-(5-tetrazolyl)amine Copper(II) Complexes

Rodríguez-Diéguez, Antonio, et al. Inorganica Chimica Acta, 2012, 385, 73-80.

Four multidimensional copper(II) complexes were synthesized by conventional and hydrothermal reactions of bis(5-tetrazolyl)amine (H2BTA) with copper(II) salts in the presence of different auxiliary ligands. These complexes have great structural diversity and exhibit antiferromagnetic and very weak ferromagnetic interactions, respectively.
Synthesis procedures of the complexes
· To prepare complex 1, Cu(BTA)(2,20 -bipy)H2O, a solution of Cu(ClO4)26H2O was added to a solution of 2,20 -bipyridine followed by the addition of H2BTA. The resulting green solution was left at room temperature for 10 days to allow green crystals to form.
· For complex 2, Cu(BTA)(1,100 -phen), a mixture containing Cu(ClO4)2 6H2O, 1,10-phenantroline, and H2BTA in water was subjected to hydrothermal treatment at 150°C for four hours. Afterward, the solution was kept at room temperature for 5 days to yield green-dark crystals.
· The preparation of complex 3, Cu2(BTA)2(H2O)4, involved the addition of copper acetate to a solution of H2BTA. The resulting solution was stirred and left at room temperature for 5 days to obtain green crystals.
· To prepare complex 4, Cu(BTA)(en)n, a mixture of Cu(ClO4)26H2O, H2BTA, ethylenediamine, and water was heated at 150°C for 4 hours in a Teflon-lined vessel. Upon slow cooling to room temperature, blue crystals of complex 4 were obtained.

Synthesis of Carboxylic Acid-Bis(tetrazolyl)amine Ligand Coordination Metal Complexes

Yang, Jie, et al. Inorganica Chimica Acta, 2014, 419, 73-81.

Five coordination metal complexes based on edtza or (datza)2- ligands were successfully synthesized, all of which exhibited photoluminescence properties at room temperature. Where edtza and (datza)2- represent ethyl-[N2(N3),N2'-di(tetrazol-5-yl) amine] acetate and di(tetrazol-5-yl)] amine-N2(N3),N2'-diacetato anion, respectively.
Synthesis procedures of the edtza-based complexes
· First, the edtza were prepared and from ethyl bromoacetate and di(tetrazol-5-yl) amine in methanolic potassium hydroxide.
· [Cd2(edtza)4(H2O)2]·2H2O (1): A solution of CdCl2·4H2O (25.54 mg, 0.1 mmol) and edzta (64.8 mg, 0.2 mmol) in 2 mL EtOH and 2 mL H2O was placed in a 25 mL Teflon-lined stainless steel vessel, sealed, and heated to 120°C for 48 hours. The resulting colorless block crystals 1 were obtained after gradual cooling to room temperature.
· [Ca(datza)(H2O)]·2H2O (2): The edzta (0.0648 g, 0.2 mmol) and KOH (0.0224 g, 0.4 mmol) were dissolved in 5 mL MeOH and 2 mL water at 100°C for 3 hours to form (datza)2-, followed by addition of CaCl2·4H2O (0.0183 g, 0.1 mmol). The mixture was stirred at 120°C for 48 hours, then cooled to room temperature slowly.
· [M(datza)(H2O)] [M = Co(3), Mn(4)]: Compounds 3 and 4 (light red crystals for 3 and colorless crystals for 4) were prepared using the same method as 2, except for substitution of zinc chlorides with MCl2·4H2O [20.19 mg (M = Co), 19.79 mg (M = Mn), 0.1 mmol].
· [Sr(datza)(H2O)] (5): Compound 5 (colorless crystals) was prepared following the procedure for compound 2, with the exception of using SrCl2·4H2O (23.06 mg, 0.1 mmol) instead of calcium chlorides.
