The crystal structures of related solid solutions in the system Ba/Pb/B/O viewed down [010]: (a) Ba8.35Pb0.65(B3O6)6; (b) Ba7.87Pb1.13(B3O6)6 (Wu et al., 2012); (c) Ba2Pb(B3O6)2 (Li et al., 2014); (d) Ba2Pb(B3O6)2 (Tang et al., 2015). The numbers indicate the bond lengths (Å) of the PbO6 or (Ba/Pb)O6 octahedra. |
