Crystal structure of the solid solution Ba_8.35Pb_0.65(B₃O₆)₆.

ABSTRACT: Single crystals of lead barium borate, Ba_8.35Pb_0.65(B₃O₆)₆, octabarium lead(II) hexa-kis-(triborate), have been obtained by spontaneous nucleation from a high-temperature melt. Its three-dimensional structure is constructed on the basis of a BaO₉ polyhedron, a (Pb/Ba)O₆ octa-hedron (occupancy ratio Pb:Ba = 0.216:0.784) and a condensed B₃O₆ ring anion. In the crystal, the planar B₃O₆ anions are stacked in an alternating fashion with Ba and (Pb/Ba) atoms along [001]. A comparison is made with the structures of related solid solutions in the system Ba/Pb/B/O.
