Materials Data on RbLiBr2 by Materials Project
RbLiBr2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are six shorter (3.53 Å) and two longer (4.03 Å) Rb–Br bond lengths. Li1+ is bonded to four Br1- atoms to form corner-sharing LiBr4 tetrahedra. There are two shorter (2.54 Å) and two longer (2.59 Å) Li–Br bond lengths. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 2-coordinate geometry to four equivalent Rb1+ and two equivalent Li1+ atoms. In the second Br1- site, Br1- is bonded to four equivalent Rb1+ and two equivalent Li1+ atoms to form a mixture of distorted edge, face, and corner-sharing BrRb4Li2 octahedra. The corner-sharing octahedral tilt angles are 67°.
