Materials Data on KMnSb by Materials Project
KMnSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five equivalent Sb3- atoms. There are four shorter (3.56 Å) and one longer (3.88 Å) K–Sb bond lengths. Mn2+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing MnSb4 tetrahedra. All Mn–Sb bond lengths are 2.80 Å. Sb3- is bonded in a 9-coordinate geometry to five equivalent K1+ and four equivalent Mn2+ atoms.
