Hf In In Ni
HfNiIn2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfNiIn2 clusters. Hf(1) is bonded in a 3-coordinate geometry to one Ni(1) and two equivalent In(1) atoms. The Hf(1)-Ni(1) bond length is 0.65 Å. Both Hf(1)-In(1) bond lengths are 0.76 Å. Ni(1) is bonded in a 3-coordinate geometry to one Hf(1) and two equivalent In(1) atoms. Both Ni(1)-In(1) bond lengths are 0.76 Å. In(1) is bonded in a 3-coordinate geometry to one Hf(1), one Ni(1), and one In(1) atom. The In(1)-In(1) bond length is 0.65 Å.
