Jw. Sibert et al., UNUSUAL COORDINATION OF HGCL2 BY A MIXED OXATHIOETHER CROWN, Journal of the Chemical Society, Chemical Communications, (15), 1994, pp. 1751-1752
The oxathioether crown 3,16-dithiacyclooctadec-14-en-14,15-dicarbonitr
ile reacts with HgCl2 to give an endocyclic complex in which macrocyli

atoms.
