K2PtC4(N2Cl)2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to three equivalent N(1), three equivalent N(2), and two equivalent Cl(1) atoms. Pt(1) is bonded in an octahedral geometry to two equivalent C(1), two equivalent C(2), and two equivalent Cl(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one Pt(1) and one N(1) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one Pt(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one C(2) atom. Cl(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one Pt(1) atom.
