The reaction of tetra-Tert-butylcyclotetraphosphane cyclo-(PtBu)4 (L) with one to four equivalents of [AuCl(tht)] (tht = tetrahydrothiophene) leads to the formation of gold(i) complexes [(AuCl)nL] (n = 1-4, 1-4) in which the ligand coordinates up to four gold(i) chloride fragments. Complexes 1-4 show dynamic behaviour with redistribution of {AuCl} moieties which was investigated by 31P{1H} NMR spectroscopy, DFT calculations and single crystal as well as powder X-ray diffraction.

Abstract
The reaction of tetra-Tert-butylcyclotetraphosphane cyclo-(PtBu)4 (L) with one to four equivalents of [AuCl(tht)] (tht = tetrahydrothiophene) leads to the formation of gold(i) complexes [(AuCl)nL] (n = 1-4, 1-4) in which the ligand coordinates up to four gold(i) chloride fragments. Complexes 1-4 show dynamic behaviour with redistribution of {AuCl} moieties which was investigated by 31P{1H} NMR spectroscopy, DFT calculations and single crystal as well as powder X-ray diffraction.
