Interaction between dopamine and the [HPW12O40](2-)Keggin ion-an X-ray and NMR study

Svensson, Fredric G.; Kessler, Vadim G.

Abstract

A novel complex between the [HPW12O40](2-) Keggin ion and the biomolecule dopamine (C8H11NO2), [HPW12O40(dop)(2)] center dot 4H(2)O (1) was crystallized and structurally characterized by single crystal X-ray diffraction and infrared spectrometry. Dopamine interacts via hydrogen bonding between its ammonium group and a W=O oxygen atom in [HPW12O40](2-). NMR analyses (H-1 DOSY) suggests that the [HPW12O40(dop)(2)] complex dissociates in D2O.
