La2LiMoO6

Dilanthanum lithium molybdenum(V) oxide has a monoclinically distorted perovskite-type structure with an ordered distribution of the Mo5+ and Li+ ions over the octahedral sites. The Mo-O distances within the slightly distorted MoO6 octahedra range between 1.959 (2) and 1.970 (2) Angstrom with an average value of 1.965 Angstrom. The LiO6 octahedra are more distorted with Li-O distances in the range 2.099 (2)-2.155 (2) Angstrom (average distance 2.132 Angstrom). The La3+ ions are surrounded by eight O atoms at distances ranging from 2.409 (3) to 2.776 (2) Angstrom with the four nearest O atoms forming a distorted tetrahedron and the remaining O atoms roughly capping two faces or bridging two edges of this tetrahedron.
