Polymorphism of Li₂Zn₃

Crystal structures of low- and high-temperature modifications of a binary phase Li₂Zn₃ were demonstrated by single-crystal X-ray diffraction techniques. The low-temperature modification is a disordered variant of Li₅Sn₂, space group . The high-temperature modification crystallizes as an anti-type to Li₅Ga₄, space group . Two polymorphs can be described as derivative structures to binary Li₅Ga₄, Li₅Sn₂, Li₁₃Sn₅, Li₈Pb₃, CeCd₂ and CdI₂ phases.
