Abstract
K5Mo8AsH4O31H2O crystallizes in the orthorhombic C222_1 space group. The structure is three-dimensional and consists of four water molecules and one K5Mo8AsH4O31 framework. In the K5Mo8AsH4O31 framework, there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.91–3.37 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.80–3.26 Å. In the third K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.91–3.13 Å. There are four inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.47 Å. In the second Mo6+ site, Mo6+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–2.46 Å. In the third Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–Omore »
