英文摘要	Single crystals of a new series of alkaline metal molybdates, LiNa3(MoO4)(2) and LiAMo(3)O(10) (A - K+, Rb+, Cs+), have been successfully synthesized through conventional high-temperature solid-state reactions. The compounds are structurally characterized by single-crystal X-ray diffraction and exhibit three-dimensional (3D) crystal structures consisting of 0D or 1D Mo-O framework. Interestingly, when Mo-O dimensionality changes from 0D of LiNa3(MoO4)(2) to 1D of LiAMo(3)O(10), the birefringence of LiAMo(3)O(10) is significantly enhanced to as large as BaTeMo2O9 and Na2TeW2O9. The differences of bandgaps induced by anionic-group dimensionality are also discussed based on structural and theoretical analyses, which illuminate that the bandgap tends to be relatively broad for compounds with isolated MoO4 tetrahedra in alkaline metal molybdate family. In addition, the dimensional reduction formalism was applied in the alkaline metal molybdate system to explore the changes of Mo-O framework along with cation/Mo ratio for the first time.
