Abstract
A bifunctional ligand H2L featuring primary (pyrazole) and secondary (acetylacetone) coordination sites was preferentially reacted with dimetallic [M2(NO3)2](NO3)2 linkers at the pyrazolyl end of H2L, giving rise to dimetallic corners. Subsequently, the corners serve as the secondary site with M' to form water-soluble organo-heterometallic [M12M'4L12] cages in a stepwise mode.
