Ni2In3 crystallizes in the trigonal P-3m1 space group. Ni(1) is bonded in a distorted body-centered cubic geometry to three equivalent In(2) and five equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to five equivalent Ni(1) atoms. In the second In site, In(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms.
Ni2In3 crystallizes in the trigonal P-3m1 space group. Ni(1) is bonded in a distorted body-centered cubic geometry to three equivalent In(2) and five equivalent In(1) atoms. All Ni(1)-In(2) bond lengths are 2.64 Å. There are a spread of Ni(1)-In(1) bond distances ranging from 2.62-2.77 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to five equivalent Ni(1) atoms. In the second In site, In(2) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms.
