StructureD 2000 Syntheses, Structure, and Bonding of Rb14(Mg1-xInx)30. A Nonstoichiometric Phase

with an Unusual Substitution in the Anion Framework. — Title compounds with x = 0.79—0.88 are synthesized by high-temperature reactions of the elements (500 °C, 10 h). As revealed by single crystal XRD, they crystallize in the space group P62m with Z = 1. The crystal structure contains two distinct types of anionic layers: isolated penta-capped trigonal prismatic clusters and condensed [(MgxIn1-x)5In14]

7- layers. The latter consists of analogous M11 (M: Mg/In) fragments that share prismatic edges and are interbridged by trigonal M3 units. — (LI, B.; CORBETT*, J. D.; Inorg. Chem. 45 (2006) 1, 156-161; Dep. Chem., Iowa State Univ., Ames, IA 50011, USA; Eng.) — W. Pewestorf
