The crystal steueture of phenoxatellurine, C₁₂H₈OTe

Abstract

Abstract The crystal structure of phenoxatellurine, C 12 H 8 OTe, was determined by X‐ray diffracto‐meter methods. The crystals are orthorhorhorhombic, P2 1 2 1 2 1 , 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.
