LiFe(MoO4)2, LiGa(MoO4)2 and Li3Ga(MoO4)3.
The structures of lithium iron dimolybdate, LiFe(MoO4)2, and lithium gallium dimolybdate, LiGa(MoO4)2, are shown to be isomorphous with each other. Their structures consist of segregated layers of LiO6 bicapped trigonal bipyramids and Fe(Ga)O6 octahedra separated and linked by layers of isolated MoO4 tetrahedra. The redetermined structure of trilithium gallium trimolybdate, Li3Ga(MoO4)3, shows substitional disorder on the Li/Ga site and consists of perpendicular chains of LiO6 trigonal prisms and two types of differently linked Li/GaO6 octahedra.
