Sr5(PtN3)2 is Krennerite-derived structured and crystallizes in the monoclinic C2/c space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. In the second Sr site, Sr(2) is bonded in a 5-coordinate geometry to one N(3), two equivalent N(1), and two equivalent N(2) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. Pt(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one N(3) atom. There are three inequivalent N sites. In the first N site, N(2) is bonded to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and one Pt(1) atom to form a mixture of distorted corner and edge-sharing NSr5Pt octahedra. The corner-sharing octahedral tilt angles range from 14-74°. In the second N site, N(3) is bonded in a 5-coordinate geometry to one Sr(2), one Sr(3), two equivalent Sr(1), and one Pt(1) atom. In the third N site, N(1) is bonded to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and one Pt(1) atom to form a mixture of distorted corner, edge, and face-sharing NSr5Pt octahedra. The corner-sharing octahedral tilt angles range from 14-74°.
