资源简介：
Rb2LaBr5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are a spread of Rb–Br bond distances ranging from 3.53–3.78 Å. La3+ is bonded to seven Br1- atoms to form distorted edge-sharing LaBr7 pentagonal bipyramids. There are a spread of La–Br bond distances ranging from 2.99–3.08 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 5-coordinate geometry to four equivalent Rb1+ and one La3+ atom. In the second Br1- site, Br1- is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two equivalent La3+ atoms. In the third Br1- site, Br1- is bonded to four equivalent Rb1+ and one La3+ atom to form a mixture of distorted corner, edge, and face-sharing BrRb4La trigonal bipyramids. In the fourth Br1- site, Br1- is bonded to four equivalent Rb1+ and one La3+ atom to form a mixture of distorted corner, edge, and face-sharing BrRb4La trigonal bipyramids.
