description: Be2MnFe2(P2O11)2 crystallizes in the trigonal P3_1 space group. The structure is three-dimensional. there are two inequivalent Be sites. In the first Be site, Be is bonded in a trigonal planar geometry to three O atoms. There are a spread of Be–O bond distances ranging from 1.50–1.59 Å. In the second Be site, Be is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.53 Å) and two longer (1.56 Å) Be–O bond length. Mn is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Mn–O bond distances ranging from 1.98–2.49 Å. There are two inequivalent Fe sites.
