Abstract

Rb3As11 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven As+0.27- atoms. There are a spread of Rb–As bond distances ranging from 3.53–3.95 Å. In the second Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven As+0.27- atoms. There are a spread of Rb–As bond distances ranging from 3.60–3.83 Å. There are six inequivalent As+0.27- sites. In the first As+0.27- site, As+0.27- is bonded to two Rb1+ and three As+0.27- atoms to form distorted AsRb2As3 square pyramids that share a cornercorner with one AsRb2As3 square pyramid, corners with five AsRbAs3 tetrahedra, corners with five AsRb2As3 trigonal bipyramids, and an edgeedge with one AsRb3As2 trigonal bipyramid. There are a spread of As–As bond distances ranging from 2.42–2.51 Å. In the second As+0.27- site, As+0.27- is bonded to one Rb1+ and three As+0.27- atoms to form distorted AsRbAs3 tetrahedra that share corners with two equivalent AsRb2As3 square pyramids, corners with two AsRbAs3 tetrahedra, and corners with four AsRb2As3 trigonal bipyramids. There are one shorter (2.43 Å) and one longer (2.51 Å) As–As bond lengths. In the third As+0.27-more »« less
