Materials Data on NaMnP by Materials Project
NaMnP is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Na1+ is bonded in a 5-coordinate geometry to five equivalent P3- atoms. There are four shorter (2.91 Å) and one longer (3.15 Å) Na–P bond lengths. Mn2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing MnP4 tetrahedra. All Mn–P bond lengths are 2.30 Å. P3- is bonded in a 9-coordinate geometry to five equivalent Na1+ and four equivalent Mn2+ atoms.
