BaNi2In crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a 4-coordinate geometry to eight equivalent Ni(1) atoms. There are a spread of Ba(1)-Ni(1) bond distances ranging from 2.72-3.36 Å. Ni(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1) and two equivalent In(1) atoms. There is one shorter (2.72 Å) and one longer (2.75 Å) Ni(1)-In(1) bond length. In(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms.
