Materials Data on RbLiCl2 by Materials Project
Abstract
RbLiCl2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are six shorter (3.36 Å) and two longer (3.76 Å) Rb–Cl bond lengths. Li1+ is bonded to four Cl1- atoms to form corner-sharing LiCl4 tetrahedra. There are two shorter (2.38 Å) and two longer (2.44 Å) Li–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to four equivalent Rb1+ and two equivalent Li1+ atoms. In the second Cl1- site, Cl1- is bonded to four equivalent Rb1+ and two equivalent Li1+ atoms to form a mixture of distorted corner, edge, and face-sharing ClRb4Li2 octahedra. The corner-sharing octahedral tilt angles are 68°.
