[en] This paper studies the molecular and crystal structures of the phenotellurazine systems. The orientation of the system of coordinates, the x axis of which coincides in direction with the line N...Te, and the different components of the dipole moment are shown. The contributions from the dipoles of the substituents are represented by the vectors of Me and Br. In the phenotellurazine system, it is shown that strong intramolecular interaction is present with shift in electron density from the aromatic rings to the heteroatoms
