Materials Data on SmIn2Cl5 by Materials Project
SmIn2Cl5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sm3+ is bonded to seven Cl1- atoms to form edge-sharing SmCl7 pentagonal bipyramids. There are a spread of Sm–Cl bond distances ranging from 2.75–2.83 Å. In1+ is bonded in a 5-coordinate geometry to five Cl1- atoms. There are a spread of In–Cl bond distances ranging from 3.20–3.29 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Sm3+ and two equivalent In1+ atoms. In the second Cl1- site, Cl1- is bonded in a water-like geometry to two equivalent Sm3+ atoms. In the third Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Sm3+ and four equivalent In1+ atoms. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Sm3+ and four equivalent In1+ atoms.
