Condensation of 2,3-dichloropyrazine with 2-aminobenzenetellurole and 2-amino-5-methylbenzenetellurole, generated in situ by\nreduction of the corresponding ditellurides, resulted in the formation of novel 10H-pyrazino[2,3-b][1,4]benzotellurazine and its\n7-methyl derivative. The products were purified via their well-crystallized 5,5-dibromo derivatives. X-ray crystallographic analysis\nof the title compound indicates that it has a pronounced V-shape and forms hydrogen-bonded dimers. Te, N-containing\nheterocycles have the potential of offering access to supramolecular assemblies.
