Title: Materials Data on KMo3Br7 by Materials Project

Abstract

KMo3Br7 crystallizes in the orthorhombic Pnnn space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six Br1- atoms to form KBr6 octahedra that share corners with six MoBr5 square pyramids. There are a spread of K–Br bond distances ranging from 3.38–3.50 Å. In the second K1+ site, K1+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are four shorter (3.34 Å) and four longer (3.63 Å) K–Br bond lengths. In the third K1+ site, K1+ is bonded in a 8-coordinate geometry to eight Br1- atoms. There are four shorter (3.34 Å) and four longer (3.63 Å) K–Br bond lengths. There are three inequivalent Mo2+ sites. In the first Mo2+ site, Mo2+ is bonded to five Br1- atoms to form MoBr5 square pyramids that share a cornercorner with one KBr6 octahedra and edges with four MoBr5 square pyramids. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mo–Br bond distances ranging from 2.61–2.63 Å. In the second Mo2+ site, Mo2+ is bonded to five Br1- atoms to form MoBr5 square pyramids that share a cornercorner with one KBr6 octahedra and edges with fourmore » MoBr5 square pyramids. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mo–Br bond distances ranging from 2.62–2.66 Å. In the third Mo2+ site, Mo2+ is bonded to five Br1- atoms to form MoBr5 square pyramids that share a cornercorner with one KBr6 octahedra and edges with four MoBr5 square pyramids. The corner-sharing octahedral tilt angles are 53°. There are a spread of Mo–Br bond distances ranging from 2.62–2.65 Å. There are seven inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 4-coordinate geometry to one K1+ and three Mo2+ atoms. In the second Br1- site, Br1- is bonded in a distorted bent 120 degrees geometry to one K1+ and one Mo2+ atom. In the third Br1- site, Br1- is bonded in a distorted trigonal planar geometry to two K1+ and one Mo2+ atom. In the fourth Br1- site, Br1- is bonded in a 8-coordinate geometry to three Mo2+ atoms. In the fifth Br1- site, Br1- is bonded in a 6-coordinate geometry to three Mo2+ atoms. In the sixth Br1- site, Br1- is bonded in a 4-coordinate geometry to one K1+ and three Mo2+ atoms. In the seventh Br1- site, Br1- is bonded in a distorted trigonal planar geometry to two K1+ and one Mo2+ atom.« less
