Solid-state binding studies of group 2 metal ions with 12-crown-4

Abstract
The mode of co-ordination of 12-crown-4 with the heavier group(II) ions Ca2+, Sr2+ and Ba2+ has been studied. Size limitations of the 12-crown-4 ligand enforced co-ordinated metal ions to reside above the macrocyclic plane, with the remaining co-ordination sphere occupied by water molecules and/or counter anions, or a second crown ether ligand to form a sandwich type species. Variation of the anion, by virtue of its co-ordinating ability, affects the structural outcome.
