Materials Data on HoInCo2 by Materials Project
HoCo2In crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. Ho is bonded in a 3-coordinate geometry to seven Co and six equivalent In atoms. There are a spread of Ho–Co bond distances ranging from 2.64–3.09 Å. There are four shorter (3.25 Å) and two longer (3.32 Å) Ho–In bond lengths. There are two inequivalent Co sites. In the first Co site, Co is bonded to four equivalent Ho, six Co, and two equivalent In atoms to form a mixture of corner, edge, and face-sharing CoHo4In2Co6 cuboctahedra. There are four shorter (2.47 Å) and two longer (2.50 Å) Co–Co bond lengths. Both Co–In bond lengths are 2.77 Å. In the second Co site, Co is bonded in a 3-coordinate geometry to three equivalent Ho, four equivalent Co, and two equivalent In atoms. Both Co–In bond lengths are 2.70 Å. In is bonded in a 12-coordinate geometry to six equivalent Ho, four Co, and two equivalent In atoms. Both In–In bond lengths are 3.28 Å.
