Materials Data on SmZn3 by Materials Project
SmZn3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to fourteen Zn atoms. There are a spread of Sm–Zn bond distances ranging from 3.04–3.51 Å. There are three inequivalent Zn sites. In the first Zn site, Zn is bonded in a 10-coordinate geometry to five equivalent Sm and five Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.60–2.81 Å. In the second Zn site, Zn is bonded in a 12-coordinate geometry to five equivalent Sm and seven Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.63–3.13 Å. In the third Zn site, Zn is bonded in a 10-coordinate geometry to four equivalent Sm and six Zn atoms.
