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-BZcis–anti–cis-dicyclohexyl-18-crown-6, isomer B; mntZmaleonitriledithiolate, 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: aZ16.709(4) A ° , bZ10.201(2) A ° , cZ33.038(4) A ° , bZ90.143(2), VZ5631.3(18) A ° 3, ZZ4, R1Z0.0679, wR2Z0.1280. The complex shows a 2D network structure consisting of [K(DC18C6-B)]C complex cations and [Pt(mnt)2]2K complex anions bridged by K–N coordinate bonds and Pt/K, K/S weak interactions. q 2004 Elsevier B.V.
