The compound described by U3Ga2Ge3 crystallizes in the tetragonal I4cm space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 8-coordinate geometry to three equivalent Ga(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second U site, U(2) is bonded in a 10-coordinate geometry to four equivalent Ga(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. Ga(1) is bonded in a 8-coordinate geometry to two equivalent U(2), three equivalent U(1), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to two equivalent U(2), three equivalent U(1), and three equivalent Ga(1) atoms. In the second Ge site, Ge(2) is bonded to two equivalent U(2) and four equivalent U(1) atoms to form corner-sharing GeU6 octahedra. The corner-sharing octahedral tilt angles range from 0-42°. is represented by the Crystallographic Information File (CIF) [CIF]
