The crystal structure described by Sr4PtN4 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to three equivalent Pt(1) and two equivalent N(3) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to two equivalent Pt(1), one N(1), one N(3), two equivalent N(4), and three equivalent N(2) atoms. In the third Sr site, Sr(3) is bonded in a 3-coordinate geometry to two equivalent Pt(1), one N(4), and two equivalent N(1) atoms. In the fourth Sr site, Sr(4) is bonded in a 7-coordinate geometry to one Pt(1), one N(1), one N(3), two equivalent N(2), and two equivalent N(4) atoms. Pt(1) is bonded in a 8-coordinate geometry to one Sr(4), two equivalent Sr(2), two equivalent Sr(3), and three equivalent Sr(1) atoms. There are four inequivalent N sites. In the first N site, N(4) is bonded in a 6-coordinate geometry to one Sr(3), two equivalent Sr(2), two equivalent Sr(4), and one N(2) atom. In the second N site, N(1) is bonded to one Sr(2), one Sr(4), two equivalent Sr(3), and one N(3) atom to form distorted corner-sharing NSr4N trigonal bipyramids. In the third N site, N(2) is bonded in a 6-coordinate geometry to two equivalent Sr(4), three equivalent Sr(2), and one N(4) atom. In the fourth N site, N(3) is bonded in a 5-coordinate geometry to one Sr(2), one Sr(4), two equivalent Sr(1), and one N(1) atom. is represented by the CIF card [CIF]
