Two-dimensional structural topology involving Pt⋯K and K⋯S weak interactions: complex of cis-anti-cis-dicyclohexyl-18-crown-6 with K2mnt and K2PtCl4

One inorganic-organic hybrid complex [K(DC18C6-B)]4[Pt(mnt)2]2 (DC18C6-B=cis-anti-cis-dicyclohexyl-18-crown-6, isomer B; mnt=maleonitriledithiolate, 1,2-dicyanoethylene-1,2-dithiolate) was synthesized by the reaction of cis-anti-cis-dicyclohexyl-18-crown-6 with K2mnt and K2PtCl4, and characterized by elementary analysis, 1H NMR, FT-IR and UV-visible spectroscopy. The crystal structure was determined by X-ray single crystal diffraction. The complex crystallizes monoclinic, space group P2/c with crystallographic data: a=16.709(4) Å, b=10.201(2) Å, c=33.038(4) Å, β=90.143(2), V=5631.3(18) Å3, Z=4, R1=0.0679, wR2=0.1280. The complex shows a 2D network structure consisting of [K(DC18C6-B)]+ complex cations and [Pt(mnt)2]2− complex anions bridged by K-N coordinate bonds and Pt⋯K, K⋯S weak interactions.
