BaReN3 is Esseneite-derived structured and crystallizes in the monoclinic C2/c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent N(3), and four equivalent N(2) atoms. In the second Ba site, Ba(2) is bonded to two equivalent N(3) and four equivalent N(1) atoms to form BaN6 octahedra that share corners with six equivalent Re(1)N4 tetrahedra and edges with two equivalent Ba(2)N6 octahedra. Re(1) is bonded to one N(1), one N(3), and two equivalent N(2) atoms to form ReN4 tetrahedra that share corners with three equivalent Ba(2)N6 octahedra and corners with two equivalent Re(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 27-69°. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one Ba(1), two equivalent Ba(2), and one Re(1) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Re(1) atoms. In the third N site, N(3) is bonded in a distorted T-shaped geometry to one Ba(1), one Ba(2), and one Re(1) atom.
BaReN3 is Esseneite-derived structured and crystallizes in the monoclinic C2/c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent N(3), and four equivalent N(2) atoms. Both Ba(1)-N(1) bond lengths are 2.97 Å. Both Ba(1)-N(3) bond lengths are 2.83 Å. There are two shorter (3.06 Å) and two longer (3.08 Å) Ba(1)-N(2) bond lengths. In the second Ba site, Ba(2) is bonded to two equivalent N(3) and four equivalent N(1) atoms to form BaN6 octahedra that share corners with six equivalent Re(1)N4 tetrahedra and edges with two equivalent Ba(2)N6 octahedra. Both Ba(2)-N(3) bond lengths are 2.70 Å. There are two shorter (2.74 Å) and two longer (2.84 Å) Ba(2)-N(1) bond lengths. Re(1) is bonded to one N(1), one N(3), and two equivalent N(2) atoms to form ReN4 tetrahedra that share corners with three equivalent Ba(2)N6 octahedra and corners with two equivalent Re(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 27-69°. The Re(1)-N(1) bond length is 1.76 Å. The Re(1)-N(3) bond length is 1.74 Å. There is one shorter (1.90 Å) and one longer (1.92 Å) Re(1)-N(2) bond length. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one Ba(1), two equivalent Ba(2), and one Re(1) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Re(1) atoms.
