Article Abstract
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.

The reactions of tetrahydrofuran solutions of NBu(4)[AuR(2)] (R = C(6)F(5), C(6)Cl(5)) with TlPF(6) and 4,4'-bipyridine lead to the synthesis of the luminescent materials [Tl(bipy)](2)[Au(C(6)F(5))(2)](2) 1 and [Tl(bipy)][Tl(bipy)(0.5)(thf)][Au(C(6)Cl(5))(2)](2) 2 in high yield. The structures of these complexes, as analyzed by X-ray diffraction, consist of planar polymers formed by repetition of Tl-Au-Au-Tl (1) or Tl-Au-Tl'-Au (2) moieties linked through bidentate bridging bipy ligands.
