Materials Data on Li2Mn(SeO3)2 by Materials Project
Li2Mn(SeO3)2 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three Li2Mn(SeO3)2 sheets oriented in the (0, 0, 1) direction. Li1+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All Li–O bond lengths are 2.05 Å. Mn2+ is bonded in a distorted octahedral geometry to six equivalent O2- atoms. All Mn–O bond lengths are 2.22 Å. Se4+ is bonded in a trigonal non-coplanar geometry to three equivalent O2- atoms. All Se–O bond lengths are 1.73 Å. O2- is bonded in a 3-coordinate geometry to one Li1+, one Mn2+, and one Se4+ atom.
