Materials Data on K3MnO4 by Materials Project
K3MnO4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded to four equivalent O atoms to form distorted KO4 trigonal pyramids that share corners with four equivalent MnO4 tetrahedra and corners with four equivalent KO4 trigonal pyramids. All K–O bond lengths are 2.62 Å. In the second K site, K is bonded in a 8-coordinate geometry to four equivalent O atoms. All K–O bond lengths are 2.92 Å. Mn is bonded to four equivalent O atoms to form MnO4 tetrahedra that share corners with eight equivalent KO4 trigonal pyramids. All Mn–O bond lengths are 1.73 Å. O is bonded in a 1-coordinate geometry to three K and one Mn atom.
