The material structure described by NiGa5 crystallizes in the tetragonal I4/mcm space group. Ni(1) is bonded in a 10-coordinate geometry to two equivalent Ga(1) and eight equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted linear geometry to two equivalent Ni(1) and eight equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Ni(1), two equivalent Ga(1), and five equivalent Ga(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
