The material structure described by Er(TiGa2)2 crystallizes in the tetragonal I4/mmm space group. Er(1) is bonded in a distorted square co-planar geometry to twelve Ga(1,1,1,1) atoms. Ti(1) is bonded in a 10-coordinate geometry to two equivalent Ti(1) and eight Ga(1,1,1,1) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent Ti(1); and four Ga(1,1,1) atoms. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(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 Er(1); four equivalent Ti(1); and four Ga(1,1,1) atoms. In the fourth Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent Ti(1); and four Ga(1,1) atoms. is represented by the CIF card [CIF]
