The material described by NiNiGa crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 14-coordinate geometry to two equivalent Ni(1), six equivalent Ni(2), and six equivalent Ga(1) atoms. In the second Ni site, Ni(2) is bonded to six equivalent Ni(1) and five equivalent Ga(1) atoms to form a mixture of distorted corner and face-sharing NiGa5Ni6 trigonal bipyramids. Ga(1) is bonded in a 11-coordinate geometry to five equivalent Ni(2) and six equivalent Ni(1) atoms. is represented by the CIF file [CIF]
