Ni2Ga3 crystallizes in the trigonal P-3m1 space group. Ni(1) is bonded in a distorted body-centered cubic geometry to three equivalent Ga(2) and five equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 5-coordinate geometry to five equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms.
Ni2Ga3 crystallizes in the trigonal P-3m1 space group. Ni(1) is bonded in a distorted body-centered cubic geometry to three equivalent Ga(2) and five equivalent Ga(1) atoms. All Ni(1)-Ga(2) bond lengths are 2.42 Å. There are a spread of Ni(1)-Ga(1) bond distances ranging from 2.42-2.55 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 5-coordinate geometry to five equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms.
