Abstract

RbNb3VCl11 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded to twelve Cl1- atoms to form distorted RbCl12 cuboctahedra that share corners with two equivalent RbCl12 cuboctahedra, corners with two equivalent VCl6 octahedra, corners with ten NbCl6 octahedra, edges with two equivalent RbCl12 cuboctahedra, faces with two equivalent NbCl6 octahedra, and faces with two equivalent VCl6 octahedra. The corner-sharing octahedra tilt angles range from 35–55°. There are a spread of Rb–Cl bond distances ranging from 3.49–3.89 Å. There are two inequivalent Nb2+ sites. In the first Nb2+ site, Nb2+ is bonded to six Cl1- atoms to form distorted NbCl6 octahedra that share corners with two equivalent RbCl12 cuboctahedra, edges with two equivalent NbCl6 octahedra, faces with two equivalent RbCl12 cuboctahedra, and a faceface with one VCl6 octahedra. There are a spread of Nb–Cl bond distances ranging from 2.46–2.64 Å. In the second Nb2+ site, Nb2+ is bonded to six Cl1- atoms to form NbCl6 octahedra that share corners with four equivalent RbCl12 cuboctahedra, an edgeedge with one VCl6 octahedra, and edges with three NbCl6 octahedra.
