| Abstract: | The structures of a series of binary molybdates with the lithium cation LiM(MoO4) · H2O (M = K+, Na+, Rb+, NH 4 + ) are analyzed and compared. Except for LiNa(MoO4) · 2H2O, in all other compounds the lithium cations have a tetrahedral coordination formed by the oxygen atoms of the water molecules and molybdate groups. The structure of LiNa(MoO4) · 2H2O was found to contain a unique coordination polyhedron of lithium, i.e., a trigonal bipyramid formed by the O atoms of the water molecules and oxo anions. |
