Gold-thallium supramolecular arrays with 4,4'-bipyridine. Solvent induction of luminescent networks.

The reaction of [AuTl(C(6)Cl(5))(2)](n) with bipy at different molar ratios, solvents or crystallisation conditions affords a series of two- and three-dimensional luminescent complexes, [AuTl(C(6)Cl(5))(2)(bipy)(0.5)](n), [AuTl(C(6)Cl(5))(2)(bipy)](n), [[Tl(bipy)][Tl(bipy)(0.5)(THF)][Au(C(6)Cl(5))(2)](2)](n), [[Tl(bipy)][Tl(bipy)(0.5)(THF)][Au(C(6)Cl(5))(2)](2)xTHF](n) and [[AuTl(C(6)Cl(5))(2)(bipy)]x0.5toluene](n)(bipy = 4,4'-bipyridine; THF = tetrahydrofuran) all of them containing polymeric chains formed via unsupported Au...Tl interactions and bridging bipyridine ligands.
