SrReN2 crystallizes in the orthorhombic Cmce space group. Sr(1) is bonded in a 7-coordinate geometry to three equivalent N(1) and four equivalent N(2) atoms. Re(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(2) is bonded to four equivalent Sr(1) and two equivalent Re(1) atoms to form distorted NSr4Re2 octahedra that share corners with four equivalent N(2)Sr4Re2 octahedra, corners with eight equivalent N(1)Sr3Re2 trigonal bipyramids, edges with two equivalent N(2)Sr4Re2 octahedra, edges with four equivalent N(1)Sr3Re2 trigonal bipyramids, and faces with two equivalent N(2)Sr4Re2 octahedra. The corner-sharing octahedral tilt angles are 55°. In the second N site, N(1) is bonded to three equivalent Sr(1) and two equivalent Re(1) atoms to form distorted NSr3Re2 trigonal bipyramids that share corners with eight equivalent N(2)Sr4Re2 octahedra, corners with two equivalent N(1)Sr3Re2 trigonal bipyramids, edges with four equivalent N(2)Sr4Re2 octahedra, and edges with three equivalent N(1)Sr3Re2 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 33-63°.
SrReN2 crystallizes in the orthorhombic Cmce space group. Sr(1) is bonded in a 7-coordinate geometry to three equivalent N(1) and four equivalent N(2) atoms. There is one shorter (2.53 Å) and two longer (2.75 Å) Sr(1)-N(1) bond lengths. There are two shorter (2.72 Å) and two longer (2.82 Å) Sr(1)-N(2) bond lengths. Re(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. There is one shorter (1.89 Å) and one longer (2.11 Å) Re(1)-N(1) bond length. Both Re(1)-N(2) bond lengths are 1.97 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded to four equivalent Sr(1) and two equivalent Re(1) atoms to form distorted NSr4Re2 octahedra that share corners with four equivalent N(2)Sr4Re2 octahedra, corners with eight equivalent N(1)Sr3Re2 trigonal bipyramids, edges with two equivalent N(2)Sr4Re2 octahedra, edges with four equivalent N(1)Sr3Re2 trigonal bipyramids, and faces with two equivalent N(2)Sr4Re2 octahedra.
