to give a racemic mixture of the derivatives of aziridinotetrazoloquinoxaline 10 and 11. Their structure and the trans configuration of hydrogen atom and methyl group on the aziridine ring of compound 10 were estimated by means of 1H and 13C NMR spectroscopy, and were in accord with the results of X-ray diffraction measurements, which also provided bond lengths, and valence, torsion, and dihedral angles
