Materials Data on SrNiSn2 by Materials Project
SrNiSn2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sr is bonded in a 4-coordinate geometry to four equivalent Ni and ten Sn atoms. All Sr–Ni bond lengths are 3.54 Å. There are a spread of Sr–Sn bond distances ranging from 3.47–3.76 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Sr and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.54–2.67 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to six equivalent Sr, one Ni, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.91 Å. In the second Sn site, Sn is bonded in a 12-coordinate geometry to four equivalent Sr and four equivalent Ni atoms.
