Materials Data on YMnO3 by Materials Project

YMnO3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Y3+ is bonded in a distorted body-centered cubic geometry to six equivalent O2- atoms. All Y–O bond lengths are 2.31 Å. Mn3+ is bonded to five O2- atoms to form corner-sharing MnO5 trigonal bipyramids. There are two shorter (1.90 Å) and three longer (2.10 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three equivalent Mn3+ atoms. In the second O2- site, O2- is bonded to three equivalent Y3+ and one Mn3+ atom to form a mixture of corner and edge-sharing OY3Mn tetrahedra.

Materials Data on YMnO3 by Materials Project

YMnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Y3+ is bonded to twelve equivalent O2- atoms to form YO12 cuboctahedra that share corners with twelve equivalent YO12 cuboctahedra, faces with six equivalent YO12 cuboctahedra, and faces with eight equivalent MnO6 octahedra. All Y–O bond lengths are 2.74 Å. Mn3+ is bonded to six equivalent O2- atoms to form MnO6 octahedra that share corners with six equivalent MnO6 octahedra and faces with eight equivalent YO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mn–O bond lengths are 1.94 Å. O2- is bonded in a distorted linear geometry to four equivalent Y3+ and two equivalent Mn3+ atoms.
