Supramolecular cation of an acyclic polyether: potassium(pentaethylene glycol) in a molecular conducting nickel dithiolate salt
Abstract
The X-ray structural analysis of the title compound revealed the formation of segregated [Ni(dmit)2] (dmit = 2-thioxo-1,3-dithiol-4,5-dithiolate) columns and dimeric K+2[PEG]2 (PEG = pentaethylene glycol) supramolecular cations in the crystal; the interaction between K+ and acyclic PEG was found to be weaker that that between K+ and cyclic polyether 18-crown-6.
