Coordination chemistry of anticrowns. Synthesis and structure of the binuclear complex of perfluorinated three-mercury anticrown (o-C6F4Hg)3 with 1,2-dichloroethane

The reaction of perfluorinated three-mercury anticrown (o-C6F4Hg)3 (1) with 1,2-dichloroethane (DCE) affords the complex {[(o-C6F4Hg)3]2(ClCH2CH2Cl)}(2) containing two anticrown molecules per DCE molecule. According to the X-ray diffraction data, the DCE molecule in complex 2 acts as a bridge between molecules 1, each DCE chlorine atom being coordinated to a single mercury center of the neighboring anticrown molecules.
