Ti Mn Bi
Mn(Ti)Bi is half-Heusler structured and crystallizes in the trigonal R3m space group. Ti(1) is bonded in a single-bond geometry to four equivalent Mn(1) and one Bi(1) atom. There are three shorter (2.58 Å) and one longer (3.30 Å) Ti(1)-Mn(1) bond length. The Ti(1)-Bi(1) bond length is 1.42 Å. Mn(1) is bonded in a 10-coordinate geometry to four equivalent Ti(1) and six equivalent Bi(1) atoms. There are three shorter (2.78 Å) and three longer (3.59 Å) Mn(1)-Bi(1) bond lengths. Bi(1) is bonded in a single-bond geometry to one Ti(1) and six equivalent Mn(1) atoms.
