description: CaCrBi12(Mo2O17)2 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Ca2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are two shorter (2.33 Å) and two longer (2.35 Å) Ca–O bond lengths. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.78–1.82 Å. In the second Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.78–1.81 Å. Cr6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.66 Å) and two longer (1.68 Å) Cr–O bond length. There are six inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.22–3.05 Å.
