Deprotonated ethylenethiourea as a ligand in an unusual tetrameric gold(I) complex†
Abstract
The product of the reaction between [(etu)2Au]+Cl– (etu = imidazolidine-2-thione) and aqueous sodium hydroxide, previously described as {(etu)Au}2O, is shown by X-ray analysis to be a tetramer with four gold(I) centres and four deprotonated etu ligands acting as N,S-donors.
