The syntheses and structural characterizations of a Pt-Tl chain [{Pt(bzq)(C6F5)2}Tl(Me2CO)]n 1 and two trinuclear Pt2M clusters (NBu4)[{Pt(bzq)(C6F5)2}2Tl] 2 and [{Pt(bzq)(C6F5)2}2Pb] 3 (bzq = 7,8-benzoquinolinyl), stabilized by donor-acceptor Pt → M bonds, are reported. The one-dimensional heterometallic chain 1 is formed by alternate "Pt(bzq)(C6F5)2" and "Tl(Me2CO)" fragments, with Pt-Tl bond separations in the range of 2.961(1)-3.

Square planar complexes [Pt(CNC)L] (CNC = C,N,C-2,6-NC5H3(C6H4-2)2; L = tht (tetrahydrothiophene, SC4H8, 1), L = CN(t)Bu (2)) react with TlPF6 in different Pt/Tl molar ratios (3/1 in the case of 1 and 1/1 in the case of 2) yielding the complexes [{Pt(CNC)(tht)}3Tl](PF6) (3) and [Pt(CNC)(CN(t)Bu)Tl](PF6) (4), respectively. The structures of 3 and 4 (X-ray) show the presence of Pt→Tl dative bonds unsupported by any bridging ligands. In complex 3, the only Tl centre is simultaneously bonded to three Pt atoms forming a perfect equilateral triangle with Pt-Tl distances of 2.

To investigate the factors influencing the luminescent properties of polymetallic cycloplatinated complexes a detailed study of the photophysical and structural properties of the heteronuclear complexes [Pt2Me2(bhq)2(μ-dppy)2Ag2(μ-acetone)](BF4)2, 2, [PtMe(bhq)(dppy)Tl]PF6, 3, and [Pt2Me2(bhq)2(dppy)2Tl]PF6, 4, [bhq = benzo[h]quinoline, dppy = 2-(diphenylphosphino)pyridine] was conducted. Complexes 3 and 4 synthesized by the reaction of [PtMe(bhq)(dppy)], 1, with TlPF6 (1 or 1/2 equiv.) and stabilized by unsupported Pt-Tl bonds as revealed by multinuclear NMR spectroscopy and confirmed by X-ray crystallography for 3.

The tetranuclear [{Pt(CNC)(tht)}3Tl](PF6) (tht = tetrahydrothiophene; SC4H8; CNC = C,N,C-2,6-NC5H3(C6H4-2)2; 2) cluster has been prepared by the reaction of [Pt(CNC)(tht)] (1) and TlPF6 (molar ratio 3:1) and structurally characterized. The Tl(I) atom is bonded to three Pt(II) centers bearing a perfect trigonal coordination. The Pt(II)-Tl(I) bonds are unsupported by any bridging ligand and are the shortest of this kind reported so far [2.
