Materials Data on Tm2Co7B3 by Materials Project
Tm2Co7B3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. there are three inequivalent Tm sites. In the first Tm site, Tm is bonded in a 6-coordinate geometry to six equivalent Co atoms. All Tm–Co bond lengths are 2.88 Å. In the second Tm site, Tm is bonded in a 12-coordinate geometry to two equivalent Tm, twelve equivalent Co, and six equivalent B atoms. Both Tm–Tm bond lengths are 3.07 Å. All Tm–Co bond lengths are 2.90 Å. All Tm–B bond lengths are 2.88 Å. In the third Tm site, Tm is bonded in a 12-coordinate geometry to one Tm, twelve Co, and six equivalent B atoms. There are six shorter (2.85 Å) and six longer (2.96 Å) Tm–Co bond lengths. All Tm–B bond lengths are 2.89 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to three equivalent Tm and six equivalent Co atoms. All Co–Co bond lengths are 2.45 Å. In the second Co site, Co is bonded in a distorted L-shaped geometry to two equivalent Tm, two equivalent Co, and two equivalent B atoms. Both Co–B bond lengths are 2.05 Å. In the third Co site, Co is bonded in a distorted square co-planar geometry to four Tm and four B atoms. There are two shorter (2.07 Å) and two longer (2.08 Å) Co–B bond lengths. There are two inequivalent B sites. In the first B site, B is bonded in a 6-coordinate geometry to three equivalent Tm and six equivalent Co atoms. In the second B site, B is bonded in a 6-coordinate geometry to three equivalent Tm and six Co atoms.
