Materials Data on NaMnBi by Materials Project
NaMnBi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Na is bonded in a 5-coordinate geometry to four equivalent Mn and five equivalent Bi atoms. All Na–Mn bond lengths are 3.53 Å. There are one shorter (3.32 Å) and four longer (3.34 Å) Na–Bi bond lengths. Mn is bonded to four equivalent Na and four equivalent Bi atoms to form a mixture of distorted edge and face-sharing MnNa4Bi4 tetrahedra. All Mn–Bi bond lengths are 2.86 Å. Bi is bonded in a 9-coordinate geometry to five equivalent Na and four equivalent Mn atoms.
