A Novel Stoichiometry for Chlorogold(I) Complexes: Structure of L4Au3Cl3(L =pyrrolidine)

The reaction between (tht)AuCl (tht = tetrahydrothiophene) and neat pyrrolidine (L) leads to the compound L4Au3Cl3. An X-ray structure determination reveals the presence of molecules LAuCl and ions L2Au+ and Cl−, in the ratio 2:1:1. The packing is characterised by Au.Au contacts and N-H-Cl-hydrogen bonds.
