Materials Data on Tb2(GePt3)3 by Materials Project
Tb2(Pt3Ge)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Tb3+ is bonded in a 11-coordinate geometry to eleven Pt2- atoms. There are a spread of Tb–Pt bond distances ranging from 2.97–3.21 Å. There are five inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in a 2-coordinate geometry to two equivalent Tb3+ and two equivalent Ge4+ atoms. Both Pt–Ge bond lengths are 2.49 Å. In the second Pt2- site, Pt2- is bonded in a 12-coordinate geometry to three equivalent Tb3+ and three Ge4+ atoms. There are a spread of Pt–Ge bond distances ranging from 2.53–2.75 Å. In the third Pt2- site, Pt2- is bonded in a 12-coordinate geometry to three equivalent Tb3+ and three Ge4+ atoms. There are one shorter (2.57 Å) and two longer (2.71 Å) Pt–Ge bond lengths. In the fourth Pt2- site, Pt2- is bonded in a 2-coordinate geometry to two equivalent Tb3+ and two Ge4+ atoms. There are one shorter (2.47 Å) and one longer (2.51 Å) Pt–Ge bond lengths. In the fifth Pt2- site, Pt2- is bonded in a 3-coordinate geometry to two equivalent Tb3+ and three Ge4+ atoms. There are a spread of Pt–Ge bond distances ranging from 2.65–2.93 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded in a 8-coordinate geometry to eight Pt2- atoms. In the second Ge4+ site, Ge4+ is bonded in a distorted hexagonal bipyramidal geometry to eight Pt2- atoms.
