Synthesis and Crystal Structure of One-dimensional Chain Complexes [K(18-C-6)]2[M(mnt)2](M=Zn, Hg)

Abstract

Abstract: The reactions of 18-crown-6 with each of K₂[M(mnt)₂](M=Zn, Hg; mnt=1,2-dicyanoethene-1,2-dithiolate, C₂S₂(CN)₂^2-) were studied and novel complexes [K(18-C-6)]₂[Zn(mnt)₂](1) and [K(18-C-6)]₂[Hg(mnt)₂](2) were characterized by elemental analysis, IR spectrum and X-ray diffraction analysis. Complex 1 displays a one-dimensional chain of [K(18-C-6)]₂[Zn(mnt)₂] bridged by K-O interactions between adjacent [K(18-C-6)]⁺ units. Complex 2 is also a one-dimensional chain of [K(18-C-6)]₂[Hg(mnt)₂] bridged by K...S weak interactions between adjacent [K(18-C-6)]⁺ and [Hg(mnt)₂]_2-.
