Crystal structure of Zn(ZnCl4)2(Cho)2: the transformation of ions to neutral species in a deep eutectic system

Chem Commun (Camb). 2017 May 11;53(39):5449-5452. doi: 10.1039/c7cc01754e.

Abstract

A neutral molecular complex, Zn(ZnCl4)2(Cho)2, has been isolated from the well-known choline chloride/ZnCl2 deep eutectic system (DES) and its crystal structure has been determined. The structure demonstrates the possibility of isolating unusual coordination complexes from DES which departs from the well-established observation of such systems being formed from large, ionic metal complexes or oligomers.
