TiGeBr2 crystallizes in the trigonal R3m space group. Ti(1) is bonded in a 10-coordinate geometry to four equivalent Ge(1), three equivalent Br(1), and three equivalent Br(2) atoms. There is one shorter (2.65 Å) and three longer (3.26 Å) Ti(1)-Ge(1) bond lengths. All Ti(1)-Br(1) bond lengths are 2.93 Å. All Ti(1)-Br(2) bond lengths are 3.15 Å. Ge(1) is bonded in a distorted linear geometry to four equivalent Ti(1) and one Br(2) atom. The Ge(1)-Br(2) bond length is 2.65 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted trigonal planar geometry to three equivalent Ti(1) and one Br(2) atom. The Br(1)-Br(2) bond length is 2.65 Å. In the second Br site, Br(2) is bonded in a 5-coordinate geometry to three equivalent Ti(1), one Ge(1), and one Br(1) atom.
