    Notes: Abstract The crystallization enthalpy of LiCl at 25°C in LiCl-H2O-cosolvent systems is determined calorimetrically as a function of the cosolvent content in the mixed solvent. This parameter is used for the investigation of heat phenomena accompanying the solvation of the salt in a saturated solution. The cosolvents employed include methanol, acetone, and N,N-dimethylformamide. The most pronounced change is effected by replacement of water with N,N-dimethylformamide.

    Notes: Abstract The crystallization enthalpies of MgCl2 in MgCl2−H2O-cosolvent systems at 25°C were determined calorimetrically as a function of the cosolvent content in the mixed solvent. Methanol, acetone, and N,N-dimethylformamide were employed as cosolvents. The results show the individual cosolvents to have very differently influences on the energy state of the salt in the saturated solution. The most pronounced changes are effected by an increase of the DMF content in the mixed solvent. The intensity of Mg2+-DMF interaction at a higher DMF content in the saturated solution considerably exceeds the Li+-DMF interaction in LiCl solutions.

    Description / Table of Contents: On the Structure of a New Modification of Phosphorus Sulfide P4S9A new modification of P4S9 is formed by the reaction of phosphorus pentasulfide with isopropanol in a molar ratio 1:4. The pure substance can be isolated by repeated fractional crystallization from CS2. This modification crystallizes in the monoclinic space group P21/n with a = 855.5 pm, b = 1263.7 pm, c = 1245.3 pm, β = 104.94°, Z = 4. Normally the P4S9 I crystallizes from its melts, only by shorttime heating the cubic modification (P4S9 II) is yielded.
    Notes: Bei der Reaktion von Phosphor(V)-sulfid mit Isopropanol im Molverhältnis 1:4 bildet sich eine neue Modifikation des P4S9. Die reine Substanz läßt sich durch mehrfache fraktionierte Kristallisation aus CS2 isolieren. Diese Modifikation kristallisiert in der monoklinen Raumgruppe P21/n mit a = 855,5 pm, b = 1263, 7 pm, c = 1245,3 pm, β = 104,94°, Z = 4. Nach kurzzeitigem Aufschmelzen kristallisiert die kubische Modifikation (P4S9 II), während längeres Schmelzen zur Kristallisation des P4S9 I führt.
