The crystal structure described by UNiGa3 crystallizes in the tetragonal I4mm space group. U(1) is bonded in a 16-coordinate geometry to four equivalent Ni(1), four equivalent Ga(1), and eight equivalent Ga(2) atoms. Ni(1) is bonded in a 5-coordinate geometry to four equivalent U(1), one Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent U(1), one Ni(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a distorted bent 120 degrees geometry to four equivalent U(1), two equivalent Ni(1), and two equivalent Ga(1) atoms. is represented by the CIF card [CIF]
