The material described by U2Zr3Ge4 crystallizes in the monoclinic P2_1/c space group. U(1) is bonded in a 7-coordinate geometry to three equivalent Ge(2) and four equivalent Ge(1) atoms. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 6-coordinate geometry to three equivalent Ge(1) and three equivalent Ge(2) atoms. In the second Zr site, Zr(2) is bonded to two equivalent Ge(1) and four equivalent Ge(2) atoms to form corner-sharing ZrGe6 octahedra. The corner-sharing octahedral tilt angles are 50°. 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 Zr(2), three equivalent Zr(1), 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 Zr(2), three equivalent Zr(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
