The material structure described by Sr7PtN6 crystallizes in the orthorhombic Ibam space group. There are three 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 SrN4 trigonal pyramids that share corners with ten equivalent Sr(2)N5 trigonal bipyramids, edges with two equivalent Sr(2)N5 trigonal bipyramids, and  an edgeedge with one Sr(1)N4 trigonal pyramid. In the second Sr site, Sr(2) is bonded to two equivalent N(2) and three equivalent N(1) atoms to form distorted SrN5 trigonal bipyramids that share corners with two equivalent Sr(2)N5 trigonal bipyramids, corners with five equivalent Sr(1)N4 trigonal pyramids, edges with five equivalent Sr(2)N5 trigonal bipyramids, and  an edgeedge with one Sr(1)N4 trigonal pyramid. In the third Sr site, Sr(3) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. Pt(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Sr(1), one Sr(3), three equivalent Sr(2), and one Pt(1) atom to form a mixture of face, corner, and edge-sharing NSr5Pt octahedra. The corner-sharing octahedral tilt angles range from 30-67°. In the second N site, N(2) is bonded in a 6-coordinate geometry to two equivalent Sr(1) and four equivalent Sr(2) atoms. is represented by the CIF file [CIF]
