Zintl-phases with layer anions: preparation and crystal structures of the isotypic compounds SrSn sub 2 As sub 2 and Sr sub 0. 87 Ba sub 0. 13 Sn sub 2 As sub 2 and a single crystal structure determination of KSnSb. Zintl-Phasen mit Schichtanionen: Darstellung und Kristallstrukturen der isotypen Verbindungen SrSn sub 2 As sub 2 und Sr sub 0,87 Ba sub 0,13 Sn sub 2 As sub 2 sowie eine Einkristallstrukturbestimmung von KSnSb

Abstract

The metallic reflecting compounds SrSn{sub 2}As{sub 2} and Sr{sub 0.87}Ba{sub 0.13}Sn{sub 2}As{sub 2} were prepared from the melt, they crystallize in the trigonal rhombohedral system (space group R3m, Z = 3) with lattice constants see ''Inhaltsuebersicht''. In the crystal structure of the isotypic compounds threebonded Sn atoms and threebonded As atoms together form puckered layers which are isostructural to grey As. The mean values of the bond lengths Sn -- As are 277.6 pm (SrSn{sub 2}As{sub 2}) and 279.1 pm (Sr{sub 0.87}Ba{sub 0.13}Sn{sub 2}As{sub 2}) resp. Along (001) the alkaline earth atoms occupy the octahedral interstices of As atoms between each second SnAs layer. The single crystal structure determination of KSnSb confirms the results of the X-ray powder analysis, but leads to slightly different values for the bond lengths.
