Materials Data on VPbF5 by Materials Project
VPbF5 crystallizes in the tetragonal I4 space group. The structure is three-dimensional. there are four inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to six F1- atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of V–F bond distances ranging from 1.87–1.99 Å. In the second V3+ site, V3+ is bonded to six F1- atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedral tilt angles are 43°. There are a spread of V–F bond distances ranging from 1.93–2.04 Å. In the third V3+ site, V3+ is bonded to six F1- atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of V–F bond distances ranging from 1.86–1.96 Å. In the fourth V3+ site, V3+ is bonded to six F1- atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedra tilt angles range from 0–43°. There are a spread of V–F bond distances ranging from 1.90–2.02 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Pb–F bond distances ranging from 2.33–2.98 Å. In the second Pb2+ site, Pb2+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Pb–F bond distances ranging from 2.45–3.13 Å. There are twelve inequivalent F1- sites.
