Materials Data on RbEu2Cl5 by Materials Project
RbEu2Cl5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Rb–Cl bond distances ranging from 3.21–3.63 Å. There are two inequivalent Eu2+ sites. In the first Eu2+ site, Eu2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Eu–Cl bond distances ranging from 2.97–3.13 Å. In the second Eu2+ site, Eu2+ is bonded to seven Cl1- atoms to form distorted edge-sharing EuCl7 pentagonal bipyramids. There are a spread of Eu–Cl bond distances ranging from 2.87–3.05 Å. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded to two equivalent Rb1+ and two equivalent Eu2+ atoms to form distorted ClRb2Eu2 tetrahedra that share corners with four equivalent ClRb2Eu3 square pyramids, corners with six ClRb2Eu2 tetrahedra, corners with two equivalent ClRb2Eu3 trigonal bipyramids, an edgeedge with one ClRb2Eu3 square pyramid, an edgeedge with one ClRb2Eu2 tetrahedra, and edges with two equivalent ClRb2Eu3 trigonal bipyramids. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to two equivalent Rb1+ and three Eu2+ atoms. In the third Cl1- site, Cl1- is bonded to two equivalent Rb1+ and three Eu2+ atoms to form distorted ClRb2Eu3 trigonal bipyramids that share corners with four equivalent ClRb2Eu3 square pyramids, corners with four ClRb2Eu2 tetrahedra, corners with four equivalent ClRb2Eu3 trigonal bipyramids, an edgeedge with one ClRb2Eu3 square pyramid, edges with four ClEu4 tetrahedra, and a faceface with one ClRb2Eu3 square pyramid. In the fourth Cl1- site, Cl1- is bonded to two equivalent Rb1+ and three Eu2+ atoms to form distorted ClRb2Eu3 square pyramids that share corners with eight ClRb2Eu2 tetrahedra, corners with four equivalent ClRb2Eu3 trigonal bipyramids, edges with two equivalent ClRb2Eu3 square pyramids, edges with two ClRb2Eu2 tetrahedra, an edgeedge with one ClRb2Eu3 trigonal bipyramid, and a faceface with one ClRb2Eu3 trigonal bipyramid. In the fifth Cl1- site, Cl1- is bonded to four Eu2+ atoms to form distorted ClEu4 tetrahedra that share corners with four equivalent ClRb2Eu3 square pyramids, corners with six ClRb2Eu2 tetrahedra, corners with two equivalent ClRb2Eu3 trigonal bipyramids, an edgeedge with one ClRb2Eu3 square pyramid, an edgeedge with one ClEu4 tetrahedra, and edges with two equivalent ClRb2Eu3 trigonal bipyramids.
