ReN2 crystallizes in the orthorhombic Immm space group. Re(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing ReN6 octahedra. The corner-sharing octahedral tilt angles are 38°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to two equivalent Re(1) and one N(1) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to four equivalent Re(1) atoms.
ReN2 crystallizes in the orthorhombic Immm space group. Re(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing ReN6 octahedra. The corner-sharing octahedral tilt angles are 38°. Both Re(1)-N(1) bond lengths are 2.00 Å. There are two shorter (1.98 Å) and two longer (2.24 Å) Re(1)-N(2) bond lengths. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to two equivalent Re(1) and one N(1) atom. The N(1)-N(1) bond length is 1.29 Å. In the second N site, N(2) is bonded in a 4-coordinate geometry to four equivalent Re(1) atoms.
