Crystal Structure of Complex of Gallocatechin Gallate and Caffeine

A merohedrally twinned crystal of the complex of (−)-gallocatechin gallate and caffeine was prepared in aqueous solution, and X-ray crystallographic analysis was performed. The driving force for the formation of the complex was thought to be mainly the π–π interaction between the B′ ring of GCg and...

Zusammenfassung:A merohedrally twinned crystal of the complex of (−)-gallocatechin gallate and caffeine was prepared in aqueous solution, and X-ray crystallographic analysis was performed. The driving force for the formation of the complex was thought to be mainly the π–π interaction between the B′ ring of GCg and caffeine, the B ring of GCg and caffeine.
