description: Cs3Mo4FeO15 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Cs–O bond distances ranging from 3.18–3.66 Å. In the second Cs1+ site, Cs1+ is bonded in a 4-coordinate geometry to seven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.02–3.51 Å. In the third Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Cs–O bond distances ranging from 3.19–3.71 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 1.75–2.53 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one FeO6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are a spread of Mo–O bond distances ranging from 1.74–1.88 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two FeO6 octahedra. The corner-sharing octahedra tilt angles range from 39–55°. There are a spread of Mo–O bond distances ranging from 1.76–1.83 Å. In the fourth Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two FeO6 octahedra. The corner-sharing octahedra tilt angles range from 35–47°. There are a spread of Mo–O bond distances ranging from 1.75–1.90 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four MoO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 2.01–2.06 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 2.02–2.04 Å.
