Abstract:
The structure of BaBi0.5Sb0.5O3 is determined by single crystal X-ray diffraction. It is an ordered perovskite, having rhombohedral symmetry, space group R (3) over bar m (No. 166), with lattice parameters a = 6.043(1) Angstrom and alpha = 60.05(2)degrees. The final agreement factor R based on F-2 for 6420 reflections was 0.052. An important structural feature of BaBi0.5Sb0.5O3 is the displacements of oxygen atoms from their ideal positions within the pseudo-cubic [110](p) planes, creating an alternative arrangement of (larger) BiO6 and (smaller) SbO6 octahedra. Therefore, the valence states of bismuth and antimony can be readily assigned as Bi(III) and Sb(V). (C) 1997 Elsevier Science Ltd.
