ChemInform Abstract
Single crystals of the title compound are prepared by annealing a pressed pellet of Ga, Ge, TmGa, and TmGe at 1103 K (Tm:Ga:Ge = 3:3:4; sealed silica tube, argon, 1 week). Tm3Ga≈2Ge≈3 belongs to the In5Bi3 branch of the Cr5B3 structure family (space group I4/mcm). The isotypic compound Lu3Ga≈2Ge≈3 is detected in the Lu—Ga—Ge system.
