Materials Data on SrLaCl5 by Materials Project

SrLaCl5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sr2+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of Sr–Cl bond distances ranging from 3.06–3.64 Å. La3+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of La–Cl bond distances ranging from 2.88–2.94 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted trigonal non-coplanar geometry to one Sr2+ and two equivalent La3+ atoms. In the second Cl1- site, Cl1- is bonded to three equivalent Sr2+ and one La3+ atom to form a mixture of distorted corner and edge-sharing ClSr3La tetrahedra. In the third Cl1- site, Cl1- is bonded in a distorted bent 150 degrees geometry to two equivalent Sr2+ and two equivalent La3+ atoms.
