TiRhZn4 crystallizes in the trigonal R3m space group. Ti(1) is bonded in a 10-coordinate geometry to four equivalent Rh(1), three equivalent Zn(1), and three equivalent Zn(2) atoms. There is one shorter (3.02 Å) and three longer (3.03 Å) Ti(1)-Rh(1) bond lengths. All Ti(1)-Zn(1) bond lengths are 2.62 Å. All Ti(1)-Zn(2) bond lengths are 2.90 Å. Rh(1) is bonded in a 13-coordinate geometry to four equivalent Ti(1), three equivalent Zn(2), and six equivalent Zn(1) atoms. All Rh(1)-Zn(2) bond lengths are 2.90 Å. There are three shorter (2.62 Å) and three longer (2.63 Å) Rh(1)-Zn(1) bond lengths. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 6-coordinate geometry to one Ti(1), two equivalent Rh(1), one Zn(2), and two equivalent Zn(1) atoms. The Zn(1)-Zn(2) bond length is 2.15 Å. Both Zn(1)-Zn(1) bond lengths are 1.24 Å. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to three equivalent Ti(1), three equivalent Rh(1), and three equivalent Zn(1) atoms.
