Furthermore, importance and usage of formazan-tetrazolyum systems have been explained. Tautomerization properties and geometric isomers based on conjugate π-system of formazans have been examined. In addition, common synthesis of these compounds and UV-visible, IR, 1H NMR spectrums used in explanation of structures have been discussed.}, number={3}, publisher={Hacettepe University}
