摘要：

All ten oxygen atoms of the acyclic oligomer 1c participate in the coordination of Ba2+ in the ''scorpion'' complex 1c. Ba(SCN)2. Me2CO. The eleventh coordination site is occupied by the acetone molecule. A further characteristic of the complex are strong O-H...N hydrogen bonds to the thiocyanate counterion. The ligands 1 also exhibit a high selectivity for cations with ionic radii of 1.2-1.3 angstrom, which could be explained with the help of molecular modeling studies.
