Abstract

Structure D 2000Crystal Structure of the 2/1 Cubic Approximant Ag42In42Yb16. -The crystal structure of the title compound is determined by single crystal XRD. It crystallizes isostructurally to Ca3Cd76 in the space group Pa3. The basic structural unit is described as a 102-atom pseudo-Bergman cluster with three successive shells, of which the second shell consists of a dodecahedron and an only nine-atom polyhedron that breaks icosahedral symmetry. -(LI*, M.
