The crystal structure described by Cs2PtC2(OF)4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to two equivalent O(1), two equivalent O(2), one F(3), three equivalent F(2), and four equivalent F(1) atoms to form distorted CsO4F8 cuboctahedra that share corners with two equivalent Cs(1)O4F8 cuboctahedra,  a cornercorner with one Pt(1)O2F4 octahedra, faces with two equivalent Cs(1)O4F8 cuboctahedra, and faces with three equivalent Pt(1)O2F4 octahedra. The corner-sharing octahedral tilt angles are 17°. In the second Cs site, Cs(2) is bonded in a 11-coordinate geometry to two equivalent O(1), two equivalent O(2), one F(2), two equivalent F(3), and four equivalent F(1) atoms. Pt(1) is bonded to two equivalent O(1), one F(2), one F(3), and two equivalent F(1) atoms to form PtO2F4 octahedra that share  a cornercorner with one Cs(1)O4F8 cuboctahedra and faces with three equivalent Cs(1)O4F8 cuboctahedra. C(1) is bonded in a bent 120 degrees geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cs(1), one Cs(2), one Pt(1), and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Cs(1), one Cs(2), and one C(1) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1), two equivalent Cs(2), and one Pt(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to one Cs(2), three equivalent Cs(1), and one Pt(1) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to one Cs(1), two equivalent Cs(2), and one Pt(1) atom. is represented by the CIF file [CIF]
