Method/Apparatus/Procedure:
   The synthetic method was used. Mixtures were prepared in a closed apparatus; components were degassed by repeated freezing, evacuation and melting; a known amount of each component was introduced into a tube by condensation and the tube was sealed. The volume of each tube was about 30 mL.

Source and Purity of Materials:
   (1) Source not specified; dried by refluxing over freshly-ignited lime, and then with aluminum amalgam, distilled.
   (2) Source not specified; chemically purified, crystallized, distilled, dried over phosphoric anhydride.
   (3) Source not specified.

Estimated Errors:
   Solubility: Not reported.
   Temperature: Composition <0.2%; temp. <0.2°C.
