Abstract

K2(MoSe6)3 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine Se+1.11- atoms. There are a spread of K–Se bond distances ranging from 3.45–4.02 Å. In the second K1+ site, K1+ is bonded in a 5-coordinate geometry to six Se+1.11- atoms. There are a spread of K–Se bond distances ranging from 3.37–3.84 Å. There are three inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to seven Se+1.11- atoms to form distorted face-sharing MoSe7 pentagonal bipyramids. There are a spread of Mo–Se bond distances ranging from 2.50–2.69 Å. In the second Mo6+ site, Mo6+ is bonded to seven Se+1.11- atoms to form distorted face-sharing MoSe7 pentagonal bipyramids. There are a spread of Mo–Se bond distances ranging from 2.54–2.68 Å. In the third Mo6+ site, Mo6+ is bonded to seven Se+1.11- atoms to form face-sharing MoSe7 pentagonal bipyramids. There are a spread of Mo–Se bond distances ranging from 2.54–2.68 Å.
