TL;DR: An unprecedented macrocyclic luminescent octanuclear cluster cyclo [Pt(C6Cl5)2(mu-OH)(mu-Ag)}4] (Pt-Ag) 2 was self-assembled by the formation of Pt(II)-Ag(I) bonds; the optical properties of this complex were also investigated.

TL;DR: The mononuclear pentafluorophenyl platinum complex containing the chelated diphenylphosphinous acid/diphenylPhosphinite system has been prepared and characterised and the related alkynyl complex forms infinite one-dimensional chains in the solid state based on intermolecular O-H[dot dot dot]O hydrogen bonding interactions.
Abstract: The mononuclear pentafluorophenyl platinum complex containing the chelated diphenylphosphinous acid/diphenylphosphinite system [Pt(C6F5){(PPh2O)2H}(PPh2OH)] 1 has been prepared and characterised. 1 and the related alkynyl complex [Pt(CCBut){(PPh2O)2H}(PPh2OH)] 2 form infinite one-dimensional chains in the solid state based on intermolecular O–H⋯O hydrogen bonding interactions. Deprotonation reactions of [PtL{(PPh2O)2H}(PPh2OH)] (L = C6F51, CCBut2, CCPh 3) with [Tl(acac)] yields tetranuclear Pt2Tl2 complexes [PtL{(PPh2O)2H}(PPh2O)Tl]2 (L = C6F54, CCBut5, CCPh 6). The structure of the tert-butylalkynyl derivative 5, established by X-ray diffraction, shows two anionic discrete units [Pt(CCBut){(PPh2O)2H}(PPh2O)]− joined by two Tl(I) centres via Tl–O and Pt–Tl bonds. Despite the existence of Pt–Tl interactions, they do not show luminescence.

TL;DR: In this article, the X-ray molecular structure of 2 was determined and the reaction of 2 and 3 with cis-[Pt(C6F5)2(thf)2] (thf = tetrahydrofuran) in the appropriate molar ratio gave the dinuclear platinum derivatives cis-[{Pt[PPh2CCR]2(µ-η 1 :η 2 C α,C β -CCC6H4CCPh)2}Pt{C 6F5]2 ][ R =t ol (4
Abstract: The ethynyltolan mononuclear complexes cis-[Pt(CCC6H4CCPh)2(PPh2CCR)2 ][ R =t ol (2), C6H4CCPh (3)], which contain (arylalkynyl)phosphane ligands, were prepared, and the X-ray molecular structure of 2 was determined. The reaction of 2 and 3 with cis-[Pt(C6F5)2(thf)2] (thf = tetrahydrofuran) in the appropriate molar ratio gave the dinuclear platinum derivatives cis-[{Pt(PPh2CCR)2(µ-η 1 :η 2 C α ,C β -CCC6H4CCPh)2}Pt(C6F5)2 ][ R =t ol (4), C6H4CCPh
