11. -4 Torr. This assembly was heated to 650 °C for 12 h, held there for a period of 6 h, then heated to 1123 K for 12 h, held for 6 h, and slowly cooled to 873 K for 12 h. At this temperature, the liquid Sn flux was filtered by centrifugation. The resulting product was metallic needlelike crystals.

15. 3 were performed with a Quantum Design PPMS commercial instrument over the temperature range 4.6-100 K in zero field by a relaxation method using the "Two-Tau Model" (ref 14b). Single crystals were mounted on the sample puck using special low-temperature grease (Quantum Design). Specific heat data were corrected for background (stage and grease).
