Materials Data on V20Ga(GeS10)4 by Materials Project
Abstract
V20Ga(GeS10)4 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. there are five inequivalent V+3.05+ sites. In the first V+3.05+ site, V+3.05+ is bonded to six S2- atoms to form distorted VS6 octahedra that share a cornercorner with one GaS4 tetrahedra, corners with two equivalent GeS4 tetrahedra, edges with four VS6 octahedra, and edges with two equivalent VS6 pentagonal pyramids. There are a spread of V–S bond distances ranging from 2.27–2.59 Å. In the second V+3.05+ site, V+3.05+ is bonded to six S2- atoms to form distorted VS6 pentagonal pyramids that share a cornercorner with one GaS4 tetrahedra, corners with two equivalent GeS4 tetrahedra, and edges with six VS6 octahedra. There are a spread of V–S bond distances ranging from 2.28–2.62 Å. In the third V+3.05+ site, V+3.05+ is bonded to six S2- atoms to form distorted VS6 octahedra that share a cornercorner with one GaS4 tetrahedra, corners with two equivalent GeS4 tetrahedra, edges with five VS6 octahedra, and an edgeedge with one VS6 pentagonal pyramid. There are a spread of V–S bond distances ranging from 2.29–2.55 Å. In the fourth V+3.05+ site, V+3.05+ is bonded to six S2- atoms to form distorted VS6 octahedra that share cornersmore »
