[Tl(OPPh3)2][Au(C6F5)2]: the first extended unsupported gold–thallium linear chain
Abstract
Li[Au(C6F5)2] reacts with TlNO3 in the presence of OPPh3 affording a complex of stoichiometry [AuTl(C6F5)2- (OPPh3)2]n, which presents different luminescence properties depending on the conditions and whose crystal structure reveals the existence of unsupported Au–Tl bonds forming a polymeric linear chain.
