Materials Data on Sm3Er by Materials Project

ErSm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er is bonded to twelve equivalent Sm atoms to form ErSm12 cuboctahedra that share corners with twelve equivalent ErSm12 cuboctahedra, edges with twenty-four equivalent SmSm8Er4 cuboctahedra, faces with six equivalent ErSm12 cuboctahedra, and faces with twelve equivalent SmSm8Er4 cuboctahedra. All Er–Sm bond lengths are 3.60 Å. Sm is bonded to four equivalent Er and eight equivalent Sm atoms to form SmSm8Er4 cuboctahedra that share corners with twelve equivalent SmSm8Er4 cuboctahedra, edges with eight equivalent ErSm12 cuboctahedra, edges with sixteen equivalent SmSm8Er4 cuboctahedra, faces with four equivalent ErSm12 cuboctahedra, and faces with fourteen equivalent SmSm8Er4 cuboctahedra. All Sm–Sm bond lengths are 3.60 Å.

Materials Data on SmEr3 by Materials Project

Er3Sm is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded to eight Er and four equivalent Sm atoms to form ErSm4Er8 cuboctahedra that share corners with twelve equivalent ErSm4Er8 cuboctahedra, edges with eight equivalent SmEr12 cuboctahedra, edges with sixteen ErSm4Er8 cuboctahedra, faces with four equivalent SmEr12 cuboctahedra, and faces with fourteen ErSm4Er8 cuboctahedra. There are four shorter (3.53 Å) and four longer (3.54 Å) Er–Er bond lengths. All Er–Sm bond lengths are 3.53 Å. In the second Er site, Er is bonded to eight equivalent Er and four equivalent Sm atoms to form ErSm4Er8 cuboctahedra that share corners with four equivalent ErSm4Er8 cuboctahedra, corners with eight equivalent SmEr12 cuboctahedra, edges with twenty-four ErSm4Er8 cuboctahedra, faces with six equivalent SmEr12 cuboctahedra, and faces with twelve ErSm4Er8 cuboctahedra. All Er–Sm bond lengths are 3.54 Å. Sm is bonded to twelve Er atoms to form SmEr12 cuboctahedra that share corners with four equivalent SmEr12 cuboctahedra, corners with eight equivalent ErSm4Er8 cuboctahedra, edges with eight equivalent SmEr12 cuboctahedra, edges with sixteen equivalent ErSm4Er8 cuboctahedra, faces with four equivalent SmEr12 cuboctahedra, and faces with fourteen ErSm4Er8 cuboctahedra.

Er3Sm is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded to eight Er and four equivalent Sm atoms to form ErSm4Er8 cuboctahedra that share corners with four equivalent SmEr12 cuboctahedra, corners with fourteen ErSm4Er8 cuboctahedra, edges with six equivalent SmEr12 cuboctahedra, edges with twelve ErSm4Er8 cuboctahedra, faces with four equivalent SmEr12 cuboctahedra, and faces with sixteen ErSm4Er8 cuboctahedra. There are a spread of Er–Er bond distances ranging from 3.50–3.63 Å. There are two shorter (3.51 Å) and two longer (3.60 Å) Er–Sm bond lengths. In the second Er site, Er is bonded to eight Er and four equivalent Sm atoms to form ErSm4Er8 cuboctahedra that share corners with four equivalent SmEr12 cuboctahedra, corners with fourteen ErSm4Er8 cuboctahedra, edges with six equivalent SmEr12 cuboctahedra, edges with twelve ErSm4Er8 cuboctahedra, faces with four equivalent SmEr12 cuboctahedra, and faces with sixteen ErSm4Er8 cuboctahedra. There are a spread of Er–Er bond distances ranging from 3.50–3.63 Å. There are two shorter (3.51 Å) and two longer (3.60 Å) Er–Sm bond lengths. In the third Er site, Er is bonded to eight Er and four equivalent Sm atoms to form ErSm4Er8 cuboctahedra that share corners with four equivalent SmEr12 cuboctahedra, corners with fourteen ErSm4Er8 cuboctahedra, edges with six equivalent SmEr12 cuboctahedra, edges with twelve ErSm4Er8 cuboctahedra, faces with four equivalent SmEr12 cuboctahedra, and faces with sixteen ErSm4Er8 cuboctahedra.
