Ab-initio determination of La
- Laboratoire des Fluorures, Universite du Maine, Le Mans Cedex (France)
The structure of La{sub 2}Mo{sub 4}O{sub 15} was determined from both high-resolution x-ray and neutron powder diffraction data. This molybdate crystallizes in a monoclinic space group P2{sub 1}/n with cell parameters a = 9.0357(2) {angstrom}, b = 12.7737(2){angstrom}, c = 10.6408(2) {angstrom}, {beta} = 90.2491(6){degree}. The structure consists of molybdenum octahedra [MoO{sub 6}] and tetrahedra [MoO], and lanthanum polyhedra [LaO{sub 9}]. Molybdenum polyhedra are connected together to form large units [Mo{sub 6}O{sub 22}], isolated by lanthanum polyhedral chains. This structure is compared with the structures of already known lanthanide molybdates with formula Ln{sub 2}Mo{sub 4}O{sub 15} (Ln=Ce,Ho).
