description: Co3B7O13I crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. there are three inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Co–O bond distances ranging from 1.92–2.43 Å. In the second Co2+ site, Co2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Co–O bond distances ranging from 1.87–2.28 Å. In the third Co2+ site, Co2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Co–O bond distances ranging from 2.03–2.39 Å. There are seven inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.44–1.56 Å. In the second B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.37–1.63 Å. In the third B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.43–1.56 Å. In the fourth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.43–1.58 Å. In the fifth B3+ site, B3+ is bonded in a distorted bent 120 degrees geometry to two O2- and one I1- atom. There is one shorter (1.34 Å) and one longer (1.35 Å) B–O bond length. The B–I bond length is 2.17 Å. In the sixth B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.44–1.56 Å. In the seventh B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.49–1.56 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Co2+ and two B3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Co2+ and one B3+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Co2+ and two B3+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Co2+ and two B3+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co2+ and two B3+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two B3+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Co2+ and two B3+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Co2+ and two B3+ atoms. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two Co2+ and two B3+ atoms. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Co2+ and two B3+ atoms. In the eleventh O2- site, O2- is bonded in a trigonal planar geometry to one Co2+ and two B3+ atoms.
