Single crystals of a Na-Ga-Si clathrate, Na<sub>8</sub>Ga<sub>5.70</sub>Si<sub>40.30</sub>, of size 2.9 mm were grown <i>via</i> the evaporation of Na from a Na-Ga-Si melt with the molar ratio of Na : Ga : Si = 4 : 1 : 2 at 773 K for 21 h under an Ar atmosphere. The crystal structure was analyzed using X-ray diffraction with the model of the type-I clathrate (cubic, <i>a</i> = 10.3266(2) Å, space group <i>Pm</i>3̄<i>n</i>, no. 223). By adding Sn to a Na-Ga-Si melt (Na : Ga : Si : Sn = 6 : 1 : 2 ...[more]
