Materials Data on RbMnSb by Materials Project
RbMnSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Rb1+ is bonded in a 5-coordinate geometry to five equivalent Sb3- atoms. There are four shorter (3.68 Å) and one longer (4.19 Å) Rb–Sb bond lengths. Mn2+ is bonded to four equivalent Sb3- atoms to form a mixture of corner and edge-sharing MnSb4 tetrahedra. All Mn–Sb bond lengths are 2.82 Å. Sb3- is bonded in a 9-coordinate geometry to five equivalent Rb1+ and four equivalent Mn2+ atoms.
