Ca5(PtN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ca sites. In the first Ca site, Ca(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 Ca site, Ca(2) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. In the third Ca site, Ca(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 Ca(1), two equivalent Ca(2), two equivalent Ca(3), and one Pt(1) atom to form a mixture of distorted corner, edge, and face-sharing NCa5Pt octahedra. The corner-sharing octahedral tilt angles range from 8-90°. In the second N site, N(3) is bonded to one Ca(1), two equivalent Ca(2), two equivalent Ca(3), and one Pt(1) atom to form a mixture of distorted corner, edge, and face-sharing NCa5Pt octahedra. The corner-sharing octahedral tilt angles range from 8-90°. In the third N site, N(1) is bonded to one Ca(1), two equivalent Ca(2), two equivalent Ca(3), and one Pt(1) atom to form a mixture of corner, edge, and face-sharing NCa5Pt octahedra. The corner-sharing octahedral tilt angles range from 10-81°.
