Crystal structure of Ti₈Bi₉O_0.25 containing inter-stitial oxygen atoms.

ABSTRACT: Single crystals of Ti₈Bi₉O_0.25, titanium bis-muth oxide (8/9/0.25), were obtained from a sample prepared by heating a mixture of Ti, TiO₂ and Bi powders in an Ar atmosphere. Single-crystal X-ray analysis revealed that the introduction of O atoms into the structure of Ti₈Bi₉ retains the space-group type P4/nmm. The oxygen site is located within a Ti₄ tetra-hedron (point group symmetry m2) that is vacant in the Ti₈Bi₉ crystal structure. The occupancy of this site is 0.25 (4), and the O-Ti distance is 1.8824 (11) Å.
