The structure described by K2Pt(CN)4 crystallizes in the orthorhombic Pccn space group. K(1) is bonded in a 8-coordinate geometry to one C(1), one C(2), three equivalent N(1), and three equivalent N(2) atoms. Pt(1) is bonded in a square co-planar geometry to two equivalent C(1) and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one K(1), one Pt(1), and one N(1) atom. In the second C site, C(2) is bonded in a distorted linear geometry to one K(1), 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 1-coordinate geometry to three equivalent K(1) and one C(1) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to three equivalent K(1) and one C(2) atom. is represented by the CIF file [CIF]
