“…BaSi 2 had been the Si-richest compound in the binary Ba−Si system before the clathrate compounds were discovered. Similarly, only La-rich phases such as La 3 Ge, La 5 Ge 3 , La 4 Ge 3 , La 5 Ge 4 , LaGe, and LaGe 2 had been reported before LaGe 5 was obtained. − …”

A new germanide, SrGe6-delta (delta congruent with 0.5), was synthesized by the reaction of Sr and Ge mixtures under a pressure of 5 GPa at 1200 degrees C. It crystallized in the orthorhombic space group Cmcm (No. 63) with a = 4.0981(6) A, b = 11.159(1) A, c = 12.6825(8) A, V = 580.0(1) A3, and Z = 4. SrGe6-delta is composed of a Ge covalent network having a cagelike structure and Sr atoms situated in the cages. Each Ge atom is coordinated by four neighboring Ge atoms. The coordination polyhedra are fairly distorted from an ideal tetrahedron, and the Ge network contains vacancies and disordering. The resistivity shows metallic behavior down to 2 K, and the positive thermoelectric power indicates the dominant carriers to be holes.

The Ge-La binary system was critically assessed by means of the calculation of phase diagram (CALPHAD) technique. The associate model was used for the liquid phase containing the constituent species Ge, La, Ge 3 La 5 , and Ge 1.7 La. The terminal solid solution diamond-(Ge) with a small solubility of La was described using the substitutional model, in which the excess Gibbs energy was formulated with the Redlich-Kister equation. The compounds with homogeneity ranges, α(Ge 1.7 La), β(Ge 1.7 La), and (GeLa), were modeled using two sublattices as α(Ge,La) 1.7 La, β(Ge,La) 1.7 La, and (Ge,La)(Ge,La), respectively. The intermediate phases with no solubility ranges, Ge 4 La 5 , Ge 3 La 4 , Ge 3 La 5 , and GeLa 3 , were treated as stoichiometric compounds. The three allotropic modifications of La, dhcp-La, fcc-La, and bcc-La, were kept as pure element phases since no solubility of Ge in La was reported. A set of self-consistent thermodynamic parameters of the Ge-La binary system was obtained. The calculation results agree well with the available experimental data from literatures.
