Materials Data on TmBPt2 by Materials Project
TmPt2B crystallizes in the hexagonal P6_222 space group. The structure is three-dimensional. Tm3+ is bonded to eight equivalent Pt and four equivalent B3- atoms to form a mixture of distorted edge, face, and corner-sharing TmB4Pt8 cuboctahedra. There are four shorter (3.00 Å) and four longer (3.10 Å) Tm–Pt bond lengths. All Tm–B bond lengths are 2.97 Å. Pt is bonded in a distorted bent 120 degrees geometry to four equivalent Tm3+ and two equivalent B3- atoms. Both Pt–B bond lengths are 2.08 Å. B3- is bonded in a 4-coordinate geometry to four equivalent Tm3+ and four equivalent Pt atoms.
