SrNiN is Potassium Silver Cyanide-derived structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted corner-sharing SrN4 tetrahedra. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to one N(1) and three equivalent N(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a linear geometry to one N(1) and one N(2) atom. In the second Ni site, Ni(2) is bonded in a linear geometry to two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing NSr4Ni2 octahedra. The corner-sharing octahedral tilt angles range from 1-67°. In the second N site, N(2) is bonded to one Sr(1), three equivalent Sr(2), one Ni(1), and one Ni(2) atom to form a mixture of distorted corner and edge-sharing NSr4Ni2 octahedra. The corner-sharing octahedral tilt angles range from 0-67°.

In the first Sr site, Sr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted corner-sharing SrN4 tetrahedra. There is one shorter (2.61 Å) and one longer (2.63 Å) Sr(1)-N(1) bond length. Both Sr(1)-N(2) bond lengths are 2.68 Å. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to one N(1) and three equivalent N(2) atoms. The Sr(2)-N(1) bond length is 2.74 Å. There are a spread of Sr(2)-N(2) bond distances ranging from 2.64-2.71 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a linear geometry to one N(1) and one N(2) atom. The Ni(1)-N(1) bond length is 1.83 Å. The Ni(1)-N(2) bond length is 1.78 Å. In the second Ni site, Ni(2) is bonded in a linear geometry to two equivalent N(2) atoms. Both Ni(2)-N(2) bond lengths are 1.75 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Ni(1) atoms to form a mixture of distorted corner and edge-sharing NSr4Ni2 octahedra.
