The material described by U2Ta3Ge4 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 6-coordinate geometry to one Ge(3), two equivalent Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 5-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. In the second Ta site, Ta(2) is bonded in a 6-coordinate geometry to one Ge(2), two equivalent Ge(3), and three equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent U(1), two equivalent Ta(1), four equivalent Ta(2), and one Ge(2) atom. In the second Ge site, Ge(1) is bonded in a 7-coordinate geometry to three equivalent U(1), one Ta(1), and three equivalent Ta(2) atoms. In the third Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent Ta(1), two equivalent Ta(2), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
