The compound described by Na3BiN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded to one N(1) and three equivalent N(2) atoms to form distorted NaN4 tetrahedra that share corners with four equivalent Bi(1)N4 tetrahedra, corners with twelve equivalent Na(1)N4 tetrahedra, edges with two equivalent Bi(1)N4 tetrahedra, and edges with four equivalent Na(1)N4 tetrahedra. Bi(1) is bonded to one N(1) and three equivalent N(2) atoms to form BiN4 tetrahedra that share corners with four equivalent Bi(1)N4 tetrahedra, corners with twelve equivalent Na(1)N4 tetrahedra, and edges with six equivalent Na(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a body-centered cubic geometry to six equivalent Na(1) and two equivalent Bi(1) atoms. In the second N site, N(2) is bonded in a body-centered cubic geometry to six equivalent Na(1) and two equivalent Bi(1) atoms. is represented by the CIF card [CIF]
