Materials Data on SrMn2O11 by Materials Project
SrMn2O11 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Sr is bonded in a distorted q6 geometry to ten O atoms. There are a spread of Sr–O bond distances ranging from 2.60–2.77 Å. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a tetrahedral geometry to four O atoms. There is one shorter (1.61 Å) and three longer (1.62 Å) Mn–O bond length. In the second Mn site, Mn is bonded in a tetrahedral geometry to four O atoms. There is one shorter (1.59 Å) and three longer (1.64 Å) Mn–O bond length. There are five inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Sr and one Mn atom. In the second O site, O is bonded in a distorted linear geometry to one Sr and one Mn atom. In the third O site, O is bonded in a single-bond geometry to one Sr atom. In the fourth O site, O is bonded in a single-bond geometry to one Mn atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Sr and one Mn atom.
