Strontium tetra­gallide

Single crystals of the title compound, SrGa₄, were synthesized from the corresponding elements using molten Sn metal as a solvent. The structure determination suggested the product to be a binary phase with composition SrGa₄, which crystallizes with the BaAl₄ type in the body-centered tetra­gonal space group I4/mmm (No. 139). The three atoms in the asymmetric unit lie on special positions with Wyckoff symbols 2a (Sr), 4d and 4e for the Ga atoms.
