Complexes of Some 1-Substituted Tetrazoles and Cobalt(II), Nickel(II), Platinum(II), and Zinc(II) Chlorides

Water‐Soluble Platinum(II) Complexes Featuring 2‐Alkyl‐2H‐tetrazol‐5‐ylacetic Acids: Synthesis, Characterization, and Antiproliferative Activity

“…By contrast to the better studied tetrazolate species, only few platinum(II) complexes with N‐substituted tetrazoles have been reported to date,, and almost no structural information on these compounds is available. In view of the recent attention to antitumor activity of tetrazole‐based cisplatin analogs, a series of cis ‐ and trans ‐isomeric platinum(II) complexes featuring N‐substituted tetrazoles have been obtained, and a few trans ‐isomeric species have been structurally characterized.…”

Advances in synthesis of tetrazoles coordinated to metal ions

“…Therefore the N 1 -and N 2 -substituted tetrazoles are involved into the formation of metal derivatives exclusively in the neutral form. [34][35][36][37][38][39][40] The metal ions can bind to the nitrogen atoms of the tetrazole ring by the coordination or the covalent type. It should be noted that in the N 1 -substituted tetrazoles the highest basicity is at the N4 atom; therefore, just this atom of the tetrazole ring in most cases takes part in the formation of the coordination bond.…”

Synthesis, Crystal Structure, and Thermal Properties of the Energetic Coordination Compound [Co(DAT)2(H2O)4](HTNR)2·2H2O (DAT = 1,5‐diaminotetrazole)

“…Traditional primary explosives, such as lead azide and lead styphnate, can lead to problems in both military and civilian fields because of their high sensitivity. As a nitrogen‐rich compound, 1,5‐diaminotetrazole (DAT) can be used as a material with high energy density and low sensitivity, and in recent years has attracted increasing attention in theoretical and experimental studies 2–6. In a large number of compounds, N–N and C–N bonds are the source of high heat of formation 7–9.…”
