Description / Table of Contents:
Preparation and Crystal Structure of (NH4)2Sb4S7(NH4)2Sb4S7 has been prepared and its structure determined. It crystallizes orthorhombic, space group Pbca, with \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm a = 1 133}{\rm .0(3) pm, b = 2625}{\rm .2(6) pm, c = 994}{\rm .0(3) pm}{\rm .} $$\end{document} Three distorted trigonal SbS3-pyramids are connected to a Sb3S3-ring in chair-conformation. These rings are bridged by further SbS3-pyramids to infinite chiralic chains.
Notes:
(NH4)2Sb4S7 wurde dargestellt und strukturell aufgeklärt. Es kristallisiert orthorhombisch, Raumgruppe Pbca, mit \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm a = 1 133,0(3) pm, b = 2625,2(6) pm, c = 994,0(3) pm}{\rm .} $$\end{document} Im Anionengitter sind jeweils 3 verzerrte trigonale SbS3-Pyramiden zu Sb3S3-Sechsringen in Sesselkonformation verknüpft. Diese Ringe sind über weitere SbS3-Pyramiden zu eindimensional unendlichen gewundenen Ketten verbunden.
