Structural diversity of alkali-metal (Li, Na, K) alkyl zincates containing bidentate aminopyrrolyl ligands: from molecular complexes to coordination polymers.

The exploration of co-complexation reactions between alkai-metal reagents and ZnEt2 with bidentate aminopyrrolyl ligands afforded a series of alkali-metal (Li, Na, K) alkyl zincates with a variety of intriguing structures, ranging from molecular complexes to more coordination polymers. All aforementioned complexes have been characterized by X-ray crystallography, NMR, IR and UV-vis spectroscopy.
