Nitrogen-tellurium-containing heterocycles. 4. X-ray structure of 2-phenylbenzotellurazole

The crystal and molecular structure of 2-phenylbenzotellurazole is determined by x-ray methods. The heterocyclic fragment of the molecule is planar. The dihedral angle between planes of the heterocycle and the 2-phenyl substituent is 31.2. Somewhat shortened Te-N intermolecular ocntacts (3.43 å) are seen in the crystal. These do not substantially affect the physical properties of the compound.For Communication 3, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1690–1692, December, 1989.
