Materials Data on TbMgTl by Materials Project

MgTbTl crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Mg is bonded in a 4-coordinate geometry to four Tl atoms. There are two shorter (2.93 Å) and two longer (2.99 Å) Mg–Tl bond lengths. Tb is bonded in a 5-coordinate geometry to five Tl atoms. All Tb–Tl bond lengths are 3.26 Å. There are two inequivalent Tl sites. In the first Tl site, Tl is bonded in a distorted q6 geometry to six equivalent Mg and three equivalent Tb atoms. In the second Tl site, Tl is bonded in a 9-coordinate geometry to three equivalent Mg and six equivalent Tb atoms.
