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.
