In Fe Ni Ni
FeNi2In is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two FeNi2In clusters. Fe(1) is bonded in a distorted single-bond geometry to two equivalent Ni(1) and one In(1) atom. Both Fe(1)-Ni(1) bond lengths are 0.70 Å. The Fe(1)-In(1) bond length is 0.43 Å. Ni(1) is bonded in a 3-coordinate geometry to one Fe(1), one Ni(1), and one In(1) atom. The Ni(1)-Ni(1) bond length is 0.43 Å. The Ni(1)-In(1) bond length is 0.70 Å. In(1) is bonded in a distorted single-bond geometry to one Fe(1) and two equivalent Ni(1) atoms.
