Crystal structure of the solid solution Ba(8.35)Pb(0.65)(B(3)O(6))(6)

Single crystals of lead barium borate, Ba(8.35)Pb(0.65)(B(3)O(6))(6), octabarium lead(II) hexa­kis­(triborate), have been obtained by spontaneous nucleation from a high-temperature melt. Its three-dimensional structure is constructed on the basis of a BaO(9) polyhedron, a (Pb/Ba)O(6) octa­hedron (oc...

Sumario:Single crystals of lead barium borate, Ba(8.35)Pb(0.65)(B(3)O(6))(6), octabarium lead(II) hexa­kis­(triborate), have been obtained by spontaneous nucleation from a high-temperature melt. Its three-dimensional structure is constructed on the basis of a BaO(9) polyhedron, a (Pb/Ba)O(6) octa­hedron (occupancy ratio Pb:Ba = 0.216:0.784) and a condensed B(3)O(6) ring anion. In the crystal, the planar B(3)O(6) 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.
