RbMnN2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 12-coordinate geometry to two equivalent N(3), four equivalent N(1), and six equivalent N(2) atoms. In the second Rb site, Rb(2) is bonded in a 12-coordinate geometry to two equivalent N(1), four equivalent N(3), and six equivalent N(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent N(2) and two equivalent N(3) atoms to form corner-sharing MnN4 tetrahedra. In the second Mn site, Mn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing MnN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to two equivalent Rb(2), four equivalent Rb(1), and two equivalent Mn(2) atoms. In the second N site, N(2) is bonded in a linear geometry to three equivalent Rb(1), three equivalent Rb(2), one Mn(1), and one Mn(2) atom. In the third N site, N(3) is bonded in a linear geometry to two equivalent Rb(1), four equivalent Rb(2), and two equivalent Mn(1) atoms.
