Supramolecular assembly of 1,3-diaminopropane and its unusual conversion by macrocyclic nickel(II) complex

Abstract

The reaction of macrocyclic nickel(II) complex [NiL](ClO 4) 2 ( 1) with 1,3-diaminopropane affords a novel complex with the formula [NiL(a.a.) 2](ClO 4) 2 ( 2), where L = 3,10- bis(2-hydroxyethyl)-1,3,5,8,10,12-hexaazacyclotetradecane, a.a. = H 3N +(CH 2) 4COO −(5-aminovaleric acid ion), which reveals that the organic ligand 1,3-diaminopropane is converted during the process of the reaction.
