Abstract
Mg5Tm crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are five inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to nine Mg and two equivalent Tm atoms. There are a spread of Mg–Mg bond distances ranging from 3.15–3.39 Å. Both Mg–Tm bond lengths are 3.26 Å. In the second Mg site, Mg is bonded in a 12-coordinate geometry to nine Mg and two equivalent Tm atoms. There are a spread of Mg–Mg bond distances ranging from 3.11–3.39 Å. Both Mg–Tm bond lengths are 3.21 Å. In the third Mg site, Mg is bonded to eleven Mg and one Tm atom to form distorted MgTmMg11 cuboctahedra that share corners with twelve MgTmMg11 cuboctahedra, edges with four equivalent TmTm2Mg10 cuboctahedra, edges with five MgTm2Mg10 cuboctahedra, faces with four equivalent TmTm2Mg10 cuboctahedra, and faces with ten MgTmMg11 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.25–3.41 Å. The Mg–Tm bond length is 3.32 Å. In the fourth Mg site, Mg is bonded to ten Mg and two equivalent Tm atoms to form distorted MgTm2Mg10 cuboctahedra that share corners with six equivalent MgTm2Mg10 cuboctahedra, corners with six equivalent TmTm2Mg10 cuboctahedra,more »
