title: Lanthanum ruthenium indide, La(21)Ru(9+x)In(5-x) (x = 1.2).
abstract: La(21)Ru(9+x)In(5-x) (Pearson symbol tI140) is isotypic to the filled Y(3)Rh(2)-type structure, from which it can be derived through an ordered substitution at two sites. One of the square-prismatic sites (site symmetry ..m) is occupied by a mixture of Ru and In atoms and one of the square-antiprismatic sites (4/m..) is fully occupied by In atoms.
