Three new alkali-metal mixed borates,
LiNaB<sub>8</sub>O<sub>13</sub>, α-LiKB<sub>8</sub>O<sub>13</sub>, and β-LiKB<sub>8</sub>O<sub>13</sub>, containing a <sup>3</sup><sub>∞</sub>[B<sub>8</sub>O<sub>13</sub>] three-dimensional
network have been successfully synthesized. Their fundamental building
block is [B<sub>8</sub>O<sub>16</sub>]<sup>8–</sup> formed
by the vertex-sharing [B<sub>5</sub>O<sub>10</sub>]<sup>5–</sup> and [B<sub>3</sub>O<sub>7</sub>]<sup>5–</sup> 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.
