Abstract

Abstract The reactions of benzo-18-crown-6 with MeX2 (Me = Cd, Hg; X = Cl. Br), and of dibenzo-18-crown-6 with Hg(CN)2 afford the compounds [Me(benzo-18-crown-6)X2] (1-4) and [Hg(dibenzo-18-crown-6)(CN)2 (5), resp., the crystal structures of which were determined. They consist of isolated neutral molecules, the crystalline Cd complexes and 5 contain one molecule of water of crystallization per formula unit, which however is not coordinated to the metal atom. The metal atoms are coordinated by the six O atoms of the ligands and the two halide atoms, or the two CN groups for 5, resp., the coordination being more unsymmetrical for the benzo than for the dibenzo ligand.
