The structure described by Ba2ReN3 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 7-coordinate geometry to two equivalent N(1), two equivalent N(3), and three equivalent N(2) atoms. In the second Ba site, Ba(2) is bonded to two equivalent N(1), two equivalent N(2), and three equivalent N(3) atoms to form distorted BaN7 pentagonal bipyramids that share corners with four equivalent Ba(2)N7 pentagonal bipyramids,  a cornercorner with one Re(1)N4 tetrahedra, edges with three equivalent Ba(2)N7 pentagonal bipyramids, and edges with four equivalent Re(1)N4 tetrahedra. Re(1) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form ReN4 tetrahedra that share  a cornercorner with one Ba(2)N7 pentagonal bipyramid, corners with two equivalent Re(1)N4 tetrahedra, and edges with four equivalent Ba(2)N7 pentagonal bipyramids. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), and two equivalent Re(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to two equivalent Ba(2), three equivalent Ba(1), and one Re(1) atom. In the third N site, N(3) is bonded in a 6-coordinate geometry to two equivalent Ba(1), three equivalent Ba(2), and one Re(1) atom. is represented by the CIF card [CIF]
