The material structure described by NaMgMnO2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a linear geometry to one O(1) and one O(2) atom. Mg(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Mn(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), two equivalent Mg(1), and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing ONaMg2Mn2 trigonal bipyramids. In the second O site, O(2) is bonded to one Na(1), two equivalent Mg(1), and two equivalent Mn(1) atoms to form a mixture of edge and corner-sharing ONaMg2Mn2 trigonal bipyramids. is represented by the CIF card [CIF]
