Absence of neutral alkali atoms in rhodizite.
The formula CsB(l2)Be(4)Al(4)O(28) has been proposed by others for the mineral rhodizite. Electron-spin-resonance and magnetic susceptibility measurements prove the absence of neutral cesium atoms. An ionic formula CsB(11)Be(4)Al(4)O(26)(OH)(2) is proposed.
