description: BaLa3Mn4O10 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.61–3.10 Å. There are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.33–3.07 Å. In the second La3+ site, La3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of La–O bond distances ranging from 2.30–2.68 Å. In the third La3+ site, La3+ is bonded in a 7-coordinate geometry to seven O2- atoms.

In the first Mn+2.25+ site, Mn+2.25+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent MnO6 octahedra and corners with two MnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 1–19°. There are a spread of Mn–O bond distances ranging from 2.08–2.31 Å. In the second Mn+2.25+ site, Mn+2.25+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent MnO6 octahedra and corners with two MnO4 tetrahedra. The corner-sharing octahedra tilt angles range from 1–19°. There are a spread of Mn–O bond distances ranging from 1.96–2.42 Å. In the third Mn+2.25+ site, Mn+2.25+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with two MnO6 octahedra and corners with two equivalent MnO4 tetrahedra.

In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, one La3+, and two Mn+2.25+ atoms. In the fifth O2- site, O2- is bonded to one Ba2+, one La3+, and two Mn+2.25+ atoms to form distorted OBaLaMn2 tetrahedra that share corners with two equivalent OBaLa3Mn2 octahedra and corners with two equivalent OLa2Mn2 tetrahedra. The corner-sharing octahedra tilt angles range from 51–67°. In the sixth O2- site, O2- is bonded to two La3+ and two Mn+2.25+ atoms to form OLa2Mn2 tetrahedra that share corners with two equivalent OBaLa3Mn2 octahedra and corners with two equivalent OBaLaMn2 tetrahedra.
