| Abstract: | The crystal structure of phenoxatellurine, C12H8OTe, was determined by X-ray diffracto-meter methods. The crystals are orthorhorhorhombic, P21 21 21, a = 6.036(1), b = 8.160(1), c = 20.717(5) Å at t = 22°. The positions of all atoms, including hydrogen, were found. The central ring is folded along the Te-O axis (138°). Average bond distances are Te-C = 2.098, C-O = 1.397, C-C = 1.382 Å. The phenyl rings are planar with a dihedral angle of 145°; C-Te-C = 89.4(3)°, C-O-C = 121.2(5)°. The structure is compared to those of phenoxathionine and pheuothiazine. |
