TiNbGa2 crystallizes in the trigonal R3m space group. Ti(1) is bonded in a distorted linear geometry to three equivalent Nb(1), one Ga(1), and four equivalent Ga(2) atoms. All Ti(1)-Nb(1) bond lengths are 2.71 Å. The Ti(1)-Ga(1) bond length is 2.09 Å. There is one shorter (2.31 Å) and three longer (2.97 Å) Ti(1)-Ga(2) bond lengths. Nb(1) is bonded in a 10-coordinate geometry to three equivalent Ti(1), three equivalent Ga(2), and four equivalent Ga(1) atoms. All Nb(1)-Ga(2) bond lengths are 2.71 Å. There is one shorter (2.31 Å) and three longer (2.97 Å) Nb(1)-Ga(1) bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted linear geometry to one Ti(1), four equivalent Nb(1), and three equivalent Ga(2) atoms. All Ga(1)-Ga(2) bond lengths are 2.71 Å. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to four equivalent Ti(1), three equivalent Nb(1), and three equivalent Ga(1) atoms.
