Materials Data on Tm3(In2Co)2 by Materials Project
Tm3(CoIn2)2 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. Tm is bonded in a 2-coordinate geometry to three Co and eight In atoms. There are two shorter (2.79 Å) and one longer (3.16 Å) Tm–Co bond lengths. There are a spread of Tm–In bond distances ranging from 3.15–3.43 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent In atoms. All Co–In bond lengths are 2.70 Å. In the second Co site, Co is bonded in a 6-coordinate geometry to six equivalent Tm and three equivalent In atoms. All Co–In bond lengths are 3.01 Å. There are two inequivalent In sites. In the first In site, In is bonded in a 10-coordinate geometry to six equivalent Tm, three Co, and one In atom. The In–In bond length is 2.97 Å. In the second In site, In is bonded in a 9-coordinate geometry to six equivalent Tm and three equivalent In atoms.
