Re-investigation of Cd₂B₂O₅: evidence of a centre of symmetry

M. Weil

Abstract: The previously determined structure of cadmium diborate, Cd₂B₂O₅, has been re-investigated and a change in space-group symmetry from P1 to P $\overline 1$ evidenced. Cd₂B₂O₅ crystallizes isotypically with other triclinic members of the M₂B₂O₅ (M = Mg, Mn, Co, Fe) family and is composed of slightly distorted [CdO₆] octahedra, forming ribbons built of four condensed single-chains and diborate anions, B₂O₅^2-, which are composed of corner-sharing BO₃ triangles and which interconnect adjacent ribbons.
