W. Radeckaparyzek et E. Luks, THE SCANDIUM(III) ION AS A TEMPLATE FOR THE SYNTHESIS OF A HEXAAZA SCHIFF-BASE MACROCYCLIC LIGAND, Monatshefte fuer Chemie, 126(6-7), 1995, pp. 795-798
The condensation of 2,6-diacetylpyridine and m-phenylenediamine in the
presence of scandium(III) perchlorate as a template agent affords a n
ew 20-membered macrocyclic complex of formula ScL(ClO4)(3) . 4H(2)O, w
here L is Me(4)bzo(2)pyo(2) [20]octaene-N-6.
