The material described by Sr3(MoN2)2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form edge-sharing MoN4 tetrahedra. In the second Mo site, Mo(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing MoN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to two equivalent Sr(2), three equivalent Sr(1), one Mo(1), and one Mo(2) atom. In the second N site, N(2) is bonded to one Sr(2), three equivalent Sr(1), one Mo(1), and one Mo(2) atom to form a mixture of distorted corner, face, and edge-sharing NSr4Mo2 octahedra. The corner-sharing octahedral tilt angles range from 43-65°. is represented by the CIF file [CIF]
