Materials Data on KMgP by Materials Project
KMgP 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 P3- atoms. There are four shorter (3.43 Å) and one longer (3.49 Å) K–P bond lengths. Mg2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing MgP4 tetrahedra. All Mg–P bond lengths are 2.65 Å. P3- is bonded in a 9-coordinate geometry to five equivalent K1+ and four equivalent Mg2+ atoms.
