Materials Data on KMnAs by Materials Project

Kristin Persson
KMnAs 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 As3- atoms. There are four shorter (3.40 Å) and one longer (3.84 Å) K–As bond lengths. Mn2+ is bonded to four equivalent As3- atoms to form a mixture of corner and edge-sharing MnAs4 tetrahedra. All Mn–As bond lengths are 2.58 Å. As3- is bonded in a 9-coordinate geometry to...
