U3TiGe5 crystallizes in the hexagonal P6_3/mcm space group. U(1) is bonded in a 9-coordinate geometry to four equivalent Ge(2) and five equivalent Ge(1) atoms. Ti(1) is bonded to six equivalent Ge(1) atoms to form face-sharing TiGe6 octahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to five equivalent U(1) and two equivalent Ti(1) atoms to form a mixture of distorted edge, face, and corner-sharing GeU5Ti2 pentagonal bipyramids. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Ge(2) atoms.
U3TiGe5 crystallizes in the hexagonal P6_3/mcm space group. U(1) is bonded in a 9-coordinate geometry to four equivalent Ge(2) and five equivalent Ge(1) atoms. All U(1)-Ge(2) bond lengths are 3.02 Å. There are a spread of U(1)-Ge(1) bond distances ranging from 2.92-3.06 Å. Ti(1) is bonded to six equivalent Ge(1) atoms to form face-sharing TiGe6 octahedra. All Ti(1)-Ge(1) bond lengths are 2.66 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to five equivalent U(1) and two equivalent Ti(1) atoms to form a mixture of distorted edge, face, and corner-sharing GeU5Ti2 pentagonal bipyramids. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Ge(2) atoms. Both Ge(2)-Ge(2) bond lengths are 2.86 Å.
