Synthesis and crystallographic characterisation of the heterodimetallic complex [(dibenzo-18-crown-6)K(m-Cl)3Ru(h6-p-cymene)]
The triple-chlorido-bridged heterodimetallic dinuclear complex [(dibenzo-18-crown-6)K(m-Cl)3Ru(h6-p-cymene)] contg. an (h6-arene)RuII fragment and a Group 1 metal crown ether fragment was synthesized and characterized by spectroscopy and X-ray crystallog. The solid-state structure clearly reveals the presence of the triple-chlorido-bridged dinuclear complex, whereas NMR investigations in different deuteriated solvents reveal the presence of an essentially 1:1 mixt. of 1 and starting materials, indicating the presence of a dynamic equil.
