    Description / Table of Contents: The existence and methods of preparation of the nitride halogenides of barium were examined. By melting together barium and barium halogenides in the molar ratio 3:1 in nitrogen atmosphere, homogenously molten dark products were obtained which by thermal and qualitative X-ray analysis were identified as new compounds having the formulae Ba2NCl and Ba2NBr, respectively.The system Ba3N2/BaJ2 has a maximum melting point at 10 Mol-% Ba3N2. The melt partly crystallizes in yellow needles. The X-ray analysis confirms the formation of a new compound, Ba6NJ9.The heats of solution were measured and from them the enthalpies of formation were calculated.
    Notes: Existenz und Darstellung der Nitridhalogenide des Bariums wurden untersucht. Durch Zusammenschmelzen von Barium und Bariumhalogenid (Cl, Br) im Molverhältnis 3:1 in Stickstoffatmosphäre erhält man einheitlich geschmolzene, tiefschwarze Produkte, die durch thermische Analyse und qualitative Röntgenuntersuchung als neue Verbindungen der Formel Ba2NCl bzw. Ba2NBr charakterisiert werden konnten.Im System Ba2N/BaJ2 ergab die thermische Analyse ein Schmelzpunktsmaximum bei 10 Mol-% Ba3N2. Eine Schmelze dieser Zusammensetzung kristallisiert zum Teil in gelben verfilzten Nädelchen. Das erstarrte Produkt besitzt eigene Röntgeninterferenzen und wäre durch die Formel Ba6NJ9 zu beschreiben.Die Lösungsenthalpien der neuen Verbindungen wurden gemessen und daraus die Bildungsenthalpien berechnet.

    Description / Table of Contents: The heats of solution of the alkaline-earth hydride halides (MeHHal) and those of the primary substances - i. e. of the metals, hydrides, and anhydrous halides - were determined in the dilute (0.1 N) solutions of the corresponding acids at 25° C and a final concentration of 2500 moles H2O per mole of salt. These data were used in calculating the standard heats of formation of the said compounds together with the reaction enthalpies belonging to the different ways of preparing the hydride halides.Contrary to earlier observations, there is indication of limited miscibility in the system CaCl2/CaHCl in the solid state.
    Notes: Die Lösungswärmen der Erdalkalihydridhalogenide und ihrer Ausgangssubstanzen-der Metalle, der Hydride und der wasserfreien Halogenide - wurden in den zugehörigen Halogenwasserstoffsäuren bei 25° C und einer Endkonzentration von 2500 Mol H2O/Mol Salz bestimmt. Aus den erhaltenen Daten werden die Standardbilungsenthalpien dieser Stoffe sowie die Reaktionsenthalpien berechnet, die bei der Darstellung der Hydridhalogenide auf verschiedenen Wegen auftreten.Einige Beobachtungen lassen vermuten, daß entgegen früheren Befunden im System CaCl2/CaHCl begrenzte Mischbarkeit im festen Zustand besteht.
