Conjugated complexes composed of quinonediimine and palladium: controlled formation of a conjugated trimetallic macrocycle.
A triangle with a calixarene-like cone configuration: the trimetallamacrocycle [{Pd(en)(L)}3 ](6+) (1; L=N,N'-bis(4-dimethylaminophenyl)-1,4-benzoquinonediimine, en=ethylenediamine; see picture for a space-filling view). The coordination array of the redox-active π-conjugated bridging quinonediimine spacer of L and the palladium unit determines whether conjugated 1 or a conjugated polymeric complex is formed.
