Cr In Ni Ni
Ni2CrIn crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a 5-coordinate geometry to two equivalent Ni(1) and four equivalent Ni(2) atoms. There is one shorter (2.38 Å) and one longer (3.36 Å) Cr(1)-Ni(1) bond length. There are a spread of Cr(1)-Ni(2) bond distances ranging from 1.97-2.53 Å. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to two equivalent Cr(1), four equivalent Ni(1), and four equivalent In(1) atoms. All Ni(1)-Ni(1) bond lengths are 3.13 Å. There are a spread of Ni(1)-In(1) bond distances ranging from 2.43-2.90 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to four equivalent Cr(1) and one In(1) atom. The Ni(2)-In(1) bond length is 0.48 Å. In the third Ni site, Ni(1) is bonded in a 10-coordinate geometry to two equivalent Cr(1), four equivalent Ni(1), and four equivalent In(1) atoms. There is one shorter (2.38 Å) and one longer (3.36 Å) Ni(1)-Cr(1) bond length. There are a spread of Ni(1)-In(1) bond distances ranging from 2.43-2.90 Å. In(1) is bonded in a single-bond geometry to one Ni(2) and four Ni(1,1) atoms.
