Abstract
The crystal and molecular structure of diphenyl telluroxide has been determined by X-ray diffraction at room temperature. The crystals are monoclinic, space group Cc, with a= 31.310(12), b= 5.629(1), c= 18.025(6)Å, β= 139.18(1)°, U= 2 076.7(10)Å3, and Z= 8. The structure has been refined to a final R 0.038 for 1 910 independent reflections (four-circle diffractometer measurements). It consists of Ph2TeO monomers [Te–C 2.137(average), TeO 1.890 Å(average)] linked by short Te–O secondary bonds [Te–O 2.554 Å(average)] to give unsymmetrical dimers. Much longer interactions between dimers [Te ⋯ O 3.771 Å(average)] occupy the fifth positions of octahedra around each Te atom.Keywords
