Materials Data on Cs2Mn3Te4 by Materials Project
Cs2Mn3Te4 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Cs1+ is bonded in a body-centered cubic geometry to eight equivalent Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.98–4.11 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to four equivalent Te2- atoms to form a mixture of edge and corner-sharing MnTe4 tetrahedra. There are two shorter (2.76 Å) and two longer (2.79 Å) Mn–Te bond lengths. In the second Mn2+ site, Mn2+ is bonded to four equivalent Te2- atoms to form a mixture of edge and corner-sharing MnTe4 tetrahedra. All Mn–Te bond lengths are 2.77 Å. Te2- is bonded in a 7-coordinate geometry to four equivalent Cs1+ and three Mn2+ atoms.
