title: Materials Data on KMgIn(MoO4)3 by Materials Project

description: KMgIn(MoO4)3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. K1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.76–2.88 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of Mg–O bond distances ranging from 2.09–2.14 Å. There are four inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent MgO6 octahedra and corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 26–31°. There is two shorter (1.78 Å) and two longer (1.80 Å) Mo–O bond length. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent MgO6 octahedra and corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 25–31°. There are a spread of Mo–O bond distances ranging from 1.78–1.80 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent MgO6 octahedra and corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 24–34°. There is two shorter (1.77 Å) and two longer (1.82 Å) Mo–O bond length. In the fourth Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent MgO6 octahedra and corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 23–35°. There is two shorter (1.77 Å) and two longer (1.82 Å) Mo–O bond length. In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of In–O bond distances ranging from 2.15–2.17 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one In3+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one K1+, one Mg2+, and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Mg2+, and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Mg2+, and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Mo6+, and one In3+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one In3+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one In3+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Mo6+, and one In3+ atom. In the twelfth O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Mo6+, and one In3+ atom.
