Abstract:
The structure of a new lithium bismuth phosphate, LiBi(7.37)P(3)O(19), consists of infinite OBi(4) edge-sharing tetrahedral chains in the ac plane, which form Bi(2)O(2) layers parallel to the b axis. They are sandwiched between PO(4) tetrahedral and Bi polyhedral layers. The PO(4)-Bi-PO(4) layers are bridged by columns formed by one Bi polyhedron flanked on each side by LiO(4) tetrahedra. This bridging Bi atom lies on a twofold axis, special position 4e of the C2/c space group. This arrangement creates pillared open elliptical channels parallel to [010].
