General description

1,3,4-thiadiazole-2,5-dithiol undergoes copolymerization with 1+, 2+ and 3+ valent metals to form coordination polymers. It forms polymers with metals and can be useful in treatment of metal-polluted water.

Application

1,3,4-thiadiazole-2,5-dithiol (Bismuthiol I) was used in determination of tellurium in indium phosphide doped with cadmium telluride by electrothermal atomic absorption spectrometry.
