Zur Kenntnis einer neuen SrSi-Modifikation und der Phase SrGe0,76 / On a New SrSi-Modification and the New Compound SrGe0,76

Abstract

A new SrSi-modification and the new phase SrGe0,76 were prepared and their structures determined. In these compounds the elementlVatoms form planar hexagons substituted in the 1, 2, 4, 5-positions by four additional Si(Ge)atoms. In the compound SrGe0,76 there are defects in this unit in the positions 1, 2, 4, 5, while in SrSi no indications of such defects could be found.
