title: LiCe(9)Mo(16)O(35).
abstract: The structure of lithium nona-cerium hexa-deca-molybdenum penta-trideca-oxide, LiCe(9)Mo(16)O(35), is isotypic with LiNd(9)Mo(16)O(35) [Gougeon Gall, Cuny, Gautier, Le Polles, Delevoye & Trebosc (2011 ▶). Chem. Eur. J.17, 13806-13813]. It is characterized by Mo(16)O(26) (i)O(10) (a) units (where i = inner and a = apical) containing Mo(16) clusters that share some of their O atoms to form infinite molybdenum cluster chains running parallel to the b axis and separated by Li(+) and Ce(3+) cations. The Mo(16) cluster units are centred at Wyckoff positions 2c and have point-group symmetry 2/m. The Li(+) atom, in a flattened octa-hedron of O atoms, is in a 2a Wyckoff position with 2/m symmetry. The Ce(3+) cations have coordination numbers to the O atoms of 6, 9 or 10. Two Ce, two Mo and five O atoms lie on sites with m symmetry (Wyckoff site 4i), and one Ce and one O atom on sites with 2/m symmetry (Wyckoff sites 2b and 2d, respectively).
