    Description / Table of Contents: On the Limits of the Zintl Concept. The New Compound Ba7Ga4Sb9The new compound Ba7Ga4Sb9 crystallizes in the orthorhombic system, space group Pmmn (No. 59) with the lattice constants \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm a} = 1802,4(7),\quad{\rm b} = 1086,1(4),\quad{\rm c} = 710,0(3){\rm pm}. $$\end{document} GaSb4 tetrahedra are connected by common corners and edges to strings, which are connected by long Sb—Sb bonds to sheets, separated by the Ba ions. The compound is not in accordance to the Zintl concept.
    Notes: Die neue Verbindung Ba7Ga4Sb9 kristallisiert orthorhombisch in der Raumgruppe Pmmn (Nr. 59) mit den Gitterkonstanten \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm a} = 1802,4(7),\quad{\rm b} = 1086,1(4),\quad{\rm c} = 710,0(3){\rm pm}. $$\end{document} GaSb4-Tetraeder sind über gemeinsame Ecken und Kanten zu Bändern vernetzt, die über lango Sb—Sb-Bindungen zu Schichten verbunden sind. Diese Schichten sind durch die Ba-Ionen getrennt. Die Verbindung ist nach Stöchiometrie und Struktur nicht in Übereinstimmung mit dem Zintl-Konzept.
