K. Rissanen et al., AN UNUSUAL COPPER(I) COMPLEX OF A NEW MACROCYCLIC LIGAND, Journal of the Chemical Society, Chemical Communications, (10), 1994, pp. 1265-1266
The new 18-membered macrocyclic ligand ,6)dipyridina-3,7(1,4)dipiperaz
inaoctacyclophane,+ shows an allosteric effect upon complexation with
copper(I) chloride in aqueous ethanol resulting in an extraordinary co
pper complex, the structure of which has been established by X-ray dif
fraction analysis.
