Sr2AuN crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one Au(1) and four equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded in a distorted L-shaped geometry to six equivalent Au(1) and two equivalent N(1) atoms. Au(1) is bonded in a 9-coordinate geometry to one Sr(1), six equivalent Sr(2), and two equivalent Au(1) atoms. N(1) is bonded to two equivalent Sr(2) and four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing NSr6 octahedra. The corner-sharing octahedral tilt angles are 18°.
Sr2AuN crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one Au(1) and four equivalent N(1) atoms. The Sr(1)-Au(1) bond length is 3.35 Å. There are two shorter (2.60 Å) and two longer (2.68 Å) Sr(1)-N(1) bond lengths. In the second Sr site, Sr(2) is bonded in a distorted L-shaped geometry to six equivalent Au(1) and two equivalent N(1) atoms. There are two shorter (3.30 Å) and four longer (3.47 Å) Sr(2)-Au(1) bond lengths. Both Sr(2)-N(1) bond lengths are 2.59 Å. Au(1) is bonded in a 9-coordinate geometry to one Sr(1), six equivalent Sr(2), and two equivalent Au(1) atoms. Both Au(1)-Au(1) bond lengths are 3.06 Å. N(1) is bonded to two equivalent Sr(2) and four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing NSr6 octahedra. The corner-sharing octahedral tilt angles are 18°.
