Materials Data on RbMnAs by Materials Project

RbMnAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one RbMnAs sheet oriented in the (0, 0, 1) direction. Rb1+ is bonded in a 4-coordinate geometry to four equivalent As3- atoms. All Rb–As bond lengths are 3.52 Å. Mn2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing MnAs4 tetrahedra. All Mn–As bond lengths are 2.61 Å. As3- is bonded in a 8-coordinate geometry to four equivalent Rb1+ and four equivalent Mn2+ atoms.
