Complexes of some thallium(I) salts with macrocyclic crown ethers have been prepared. Complexes of benzo-15crown-5 (I) and 4,5dibromo-benzo 15-crown-5, (II), appear to have a sandwich structure where two molecules of the ligand are co-ordinated to one thallium ion. Complexes of I8-crown-6, (IV) have
## Alkaline earth metal perchlorates and thiocyanates react with cyclic polyethers to yield crystalline solids. The products are found to be influenced by cation radius and charge, and also by the reaction solvent and anion. Competition reactions between potassium and calcium are shown to be solvent
