    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.

    Description / Table of Contents: Electron Deficient Compounds of Gallium: Crystal Structure of Ca3Ga5The stoichiometry of the formerly described compound Ca2Ga3 is corrected to Ca3Ga5. This compound crystallizes in the orthorhombic system, space group Cmcm (No. 63) with the lattice constants see „Inhaltsübersicht“. In the structure there is a Ga framework for which on the basis of the Gillespie/Nyholm conception and by calculating the bond numbers according to Pauling a characteristic electron concentration can be derived.
    Notes: Die Stöchiometrie der im Ca/Ga-Zweistoffsystem beschriebenen Verbindung „Ca2Ga3“ ist zu Ca3Ga5 zu korrigieren. Sie kristallisiert orthorhombisch in der Raumgruppe Cmcm (Nr. 63) mit den Gitterkonstanten: \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm a = 446,3(2)\, pm,\qquad b = 1079,9(3)\, pm,\qquad c = 1502,5(4)\,pm} $$\end{document}. In der Struktur liegt ein Ga-Raumnetzverband vor, für den sich aus der Gillespie-Nyholm-Konzeption und den Bindungsgradzahlen nach Pauling eine charakteristische Elektronenzahl ableiten läßt.

The melting points are 440 ± 10°C for Cs2P2S6 and 508 ± 10°C for K2P2S6.
