Na3TaN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded in a 1-coordinate geometry to one N(1) and one N(2) atom. Ta(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing TaN4 trigonal pyramids. 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 Ta(1) atoms. In the second N site, N(2) is bonded in a distorted square co-planar geometry to two equivalent Na(1) and two equivalent Ta(1) atoms.
