Three new alkali-metal mixed borates, LiNaB8O13, α-LiKB8O13, and β-LiKB8O13, containing a 3[B8O13] three-dimensional network have been successfully synthesized. Their fundamental building block is [B8O16]8– formed by the vertex-sharing [B5O10]5– and [B3O7]5– groups, which are topologically identical when they are considered as four-connected nodes. The viewpoints give us a feasible way to investigate the versatile structure assembly of borates with a complex network.
