Li4Na2CsB7O14 with unique edge-sharing [BO4]5- tetrahedra, an unprecedented [B14O28]14- cluster, and high anisotropic thermal expansion has been obtained under atmospheric pressure conditions, indicating that high pressure is not essential for obtaining edge-sharing [BO4]5- tetrahedra-containing borates. In addition, Li4Na2CsB7O14 may be used as a thermal expansion material.
在常压条件下获得了具有独特的共用边[BO4]5-四面体、前所未有的[B14O28]14-簇和各向异性热膨胀的 Li4Na2CsB7O14，表明高压并不是获得含共用边[BO4]5-四面体的硼酸盐所必需的。此外，Li4Na2CsB7O14 可用作热膨胀材料。
