Abstract

The template condensation of 6,6'-bis(hydrazino)-2,2'-bipyridines or 2,9-bis(hydrazino)-1,10-phenanthrolines with 2,6-pyridine dicarbonyls in the presence of chromium(III) chloride leads to the formation of free macrocycles rather than the expected metal complexes; the origin of this 'transient-template' effect is discussed and the crystal structural analysis of a chromium(III) macrocyclic complex is described.
