Abstract

A novel beryllium borate, Ca3Na4LiBe4B10O24F, has been discovered. It possesses a unique ∞(2)[Be8B16O40F2] layer composed of two opposite parallel [Be4B4O12F]∞ layers bridged with [B12O24] polyborates. The linkage of [B12O24] to other structural units is first found in anhydrous borates. In the ∞(2)[Be8B16O40F2] layer, multiple tunnels are arranged along different directions resided by the alkali and alkaline-earth cations. The compound remains stable in an ambient atmosphere from room temperature to the melting point at 830 °C and melts incongruently.
