Description
Digallium pentatantalum tin, Mr=1162.87, tetragonal, I4/mcm, a=10.354 (2), c=5.1795 (6) A, V=555.3 A3, Z=4, Dx=13.91 Mg m-3, Mo Kα, λ=0.71069 A, μ=118.2 mm-1, F(000)=1908, room temperature, final R=0.053, wR=0.055 for 336 [vertical strokeF0vertical stroke>3σ(F0)] unique reflections. The title compound is isomorphous with W5Si3. The main characteristic of the structure is the existence of (Ga2Ta8)∞ columns parallel to the c axis. These columns are connected by Sn and Ga atoms to form a three-dimensional framework. There are two distinct sites for Ga atoms with one of them being shared equally and statistically between Ga and Sn atoms. (orig.)
