In the third N site, N(3) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent Re(1) atoms. In the fourth N site, N(4) is bonded in a 2-coordinate geometry to one Na(1) and two equivalent Re(2) atoms. In the fifth N site, N(5) is bonded to two equivalent Na(2), one Re(1), and one Re(2) atom to form distorted NNa2Re2 tetrahedra that share corners with two equivalent N(5)Na2Re2 tetrahedra, corners with three equivalent N(1)Na3Re tetrahedra, and  a cornercorner with one N(2)Na4Re trigonal bipyramid. is represented by the Crystallographic Information File (CIF) [CIF]
