The structure described by Na3CoN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. Co(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing CoN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted hexagonal bipyramidal geometry to six equivalent Na(1) and two equivalent Co(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
