摘要: The crystal structure of Li6BeF4ZrF8 has been determined by x‐ray diffraction. tetragonal unit cell, having a=6.57, c=18.62 A, contains four formula weights; the space group is D4h19—I41amd. Discrete BeF42— and ZrF84— ions are connected shared Li+ ions. tetrahedron quite regular with a Be–F distance 1.57±0.01 A; dodecahedron two independent Zr–F bonds 2.05±0.01 A 2.16±0.01 deviates considerably from shape predicted theory.
