The molecular structures of two 1,3-dithiol anellated nine membered thia crown compounds have been determined by X-ray diffraction. Their complex formation behaviour towards Ag-I and Hg-II is studied and discussed using solvent extraction experiments and molecular modeling calculations.

Crown Thioether Chemistry: Novel Silver(I) Complexes of 1,3‐Dithiole‐Annelated 1,4,7‐Trithiacyclononane
The coordination chemistry of two crownthioethers 2,5,8,10,12-pentathiabicyclo[7.3.0]dodeca-1)9)-ene-11-thione (L) and -11-one (L') with Ag1 has been investigated by structural methods. Both thioethers act as tridentate ligands coordinating the silver ion in a trigonal fashion. In the case L, the 11- thione sulfur is coordinated additionally by another silver ion, to yield a polymeric chain with a
