Cr In In Ni
CrNiIn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrNiIn2 cluster. Cr(1) is bonded in a single-bond geometry to one In(1) atom. The Cr(1)-In(1) bond length is 1.28 Å. Ni(1) is bonded in a distorted bent 120 degrees geometry to one In(1) and one In(2) atom. The Ni(1)-In(1) bond length is 1.49 Å. The Ni(1)-In(2) bond length is 1.39 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in an L-shaped geometry to one Cr(1) and one Ni(1) atom. In the second In site, In(2) is bonded in a distorted single-bond geometry to one Ni(1) atom.
