Materials Data on La2NiSn4 by Materials Project

La2NiSn4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 10-coordinate geometry to ten Sn atoms. There are a spread of La–Sn bond distances ranging from 3.31–3.58 Å. In the second La site, La is bonded in a 4-coordinate geometry to four equivalent Ni and ten Sn atoms. There are two shorter (3.52 Å) and two longer (3.55 Å) La–Ni bond lengths. There are a spread of La–Sn bond distances ranging from 3.37–3.67 Å. Ni is bonded in a 5-coordinate geometry to four equivalent La and five Sn atoms. There are a spread of Ni–Sn bond distances ranging from 2.50–2.60 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to six La, one Ni, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.92 Å. In the second Sn site, Sn is bonded in a 8-coordinate geometry to six La and two equivalent Sn atoms. In the third Sn site, Sn is bonded in a 10-coordinate geometry to four La, two equivalent Ni, and four equivalent Sn atoms. There are two shorter (3.20 Å) and two longer (3.22 Å) Sn–Sn bond lengths. In the fourth Sn site, Sn is bonded in a 10-coordinate geometry to four La, two equivalent Ni, and four equivalent Sn atoms.
