The crystal structure described by Sr(NiN)2 crystallizes in the trigonal P-3m1 space group. Sr(1) is bonded to six equivalent N(1) atoms to form distorted SrN6 octahedra that share corners with twelve equivalent Ni(1)N4 tetrahedra, edges with six equivalent Sr(1)N6 octahedra, and edges with six equivalent Ni(1)N4 tetrahedra. Ni(1) is bonded to four equivalent N(1) atoms to form NiN4 tetrahedra that share corners with six equivalent Sr(1)N6 octahedra, corners with six equivalent Ni(1)N4 tetrahedra, edges with three equivalent Sr(1)N6 octahedra, and edges with three equivalent Ni(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 27-48°. N(1) is bonded in a 7-coordinate geometry to three equivalent Sr(1) and four equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
