Sc(TiGa2)2 crystallizes in the tetragonal I4/mmm space group. Sc(1) is bonded in a distorted square co-planar geometry to twelve Ga(1,1,1) atoms. Ti(1) is bonded in a 10-coordinate geometry to two equivalent Ti(1) and eight Ga(1,1,1) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Sc(1), four equivalent Ti(1), and four equivalent Ga(1) atoms. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Sc(1); four equivalent Ti(1); and four Ga(1,1) atoms. In the third Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Sc(1), four equivalent Ti(1), and four equivalent Ga(1) atoms.
Sc(TiGa2)2 crystallizes in the tetragonal I4/mmm space group. Sc(1) is bonded in a distorted square co-planar geometry to twelve Ga(1,1,1) atoms. There are four shorter (2.80 Å) and eight longer (3.28 Å) Sc(1)-Ga(1,1,1) bond lengths. Ti(1) is bonded in a 10-coordinate geometry to two equivalent Ti(1) and eight Ga(1,1,1) atoms. Both Ti(1)-Ti(1) bond lengths are 2.70 Å. All Ti(1)-Ga(1,1,1) bond lengths are 2.73 Å. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Sc(1), four equivalent Ti(1), and four equivalent Ga(1) atoms. There are two shorter (2.62 Å) and two longer (2.86 Å) Ga(1)-Ga(1) bond lengths. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Sc(1); four equivalent Ti(1); and four Ga(1,1) atoms. Both Ga(1)-Ga(1) bond lengths are 2.62 Å. In the third Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Sc(1), four equivalent Ti(1), and four equivalent Ga(1) atoms.
