Crystal structure of [K(18-crown-6)]+ 2[Pt(CN)4]2−

Abstract

In the title compound, di-μ-cyanato-1:2κ2 N:C;2:3κ2 C:N-dicyanato-2κ2 C-bis(1,4,7,10,13,16-hexaoxacyclooctadecane)-1κ6 O;3κ6 O-1,3-dipotassium(I)-2-platinum(II), [K2Pt(CN)4(C12H24O6)2] or [K(18-crown-6)]2·[Pt(CN)4], two trans-orientated cyano groups of the square-planar [Pt(CN)4]2− dianion (Pt site symmetry \overline{1}) bind to one potassium ion each, which are additionally coordinated by the six O atoms of 18-crown-6. No Pt...Pt interactions occur in the crystal, but very weak Pt...H contacts (2.79 Å) are observed.
