LaTiGe3 crystallizes in the trigonal R3m space group. La(1) is bonded to twelve equivalent Ge(1) atoms to form distorted LaGe12 cuboctahedra that share corners with twelve equivalent La(1)Ge12 cuboctahedra, faces with six equivalent La(1)Ge12 cuboctahedra, and faces with eight equivalent Ti(1)Ge6 octahedra. There are a spread of La(1)-Ge(1) bond distances ranging from 3.03-3.87 Å. Ti(1) is bonded to six equivalent Ge(1) atoms to form TiGe6 octahedra that share corners with six equivalent Ti(1)Ge6 octahedra and faces with eight equivalent La(1)Ge12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.14 Å) and three longer (2.74 Å) Ti(1)-Ge(1) bond lengths. Ge(1) is bonded in a 1-coordinate geometry to four equivalent La(1) and two equivalent Ti(1) atoms.
