U2Mo3Ge4 is delta Molybdenum Boride-derived structured and crystallizes in the monoclinic P2_1/c space group. U(1) is bonded in a 7-coordinate geometry to two equivalent Mo(2), three equivalent Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent Ge(1) and four equivalent Ge(2) atoms to form distorted corner-sharing MoGe6 octahedra. The corner-sharing octahedral tilt angles are 48°. In the second Mo site, Mo(2) is bonded in a 8-coordinate geometry to two equivalent U(1), three equivalent Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent U(1), one Mo(1), three equivalent Mo(2), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent U(1), two equivalent Mo(1), three equivalent Mo(2), and one Ge(2) atom.
