 Method/Apparatus/Procedure:
   The synthetic method was used. Determinations were made in sealed tubes, which were heated and allowed to cool slowly in water bath. Thermometers were calibrated to 0.01 K.

 Source and Purity of Materials:
   (1) Soyuzreaktiv, USSR; CP reagent; dried over P2O5 and twice distilled in a laboratory packed column; n(20 °C, D) = 1.3440, d(20 °C, 4 °C) = 0.7828.
   (2) Soyuzreaktiv, USSR; pure grade reagent; purified by two vacuum distillations; water content by the method Fischer less than 0.04 mass. %.

 Estimated Errors:

   Temperature: ± 0.02 K.
