Abstract: A series of cyclometalated platinum(II) complexes with nitrile and isocyanide ligands (RCN and RNC; R = t-Bu, Bn, Ph) have been synthesized in 60–80% yields from the dimer [{Pt(ppy)Cl}2] (Hppy is 2-phenylpyridine) and the corresponding nitriles and isocyanides. The structure of the synthesized complexes was determined by mass spectrometry, IR and NMR spectroscopy, and X-ray diffraction. The contributions of different intermolecular interactions to the crystal packing were estimated by Hirshfeld surface analysis. Photophysical properties of the synthesized complexes in solution and solid state were studied.

The synthesis, structure and spectroscopy of a series of luminescent orthometalated square planar platinum(II) complexes are reported. Reaction of K2PtCl4 with one mole equivalent of 2-phenylpyridine (ppyH) in 2-ethoxyethanol and water (1:1 ratio) resulted in the formation of chloro-bridged dimeric precursor [Pt2(μ-Cl)2(ppy)2], which on further reactions with various anionic one-, two- and three-atom ancillary ligands, having O/N/S donors, yielded mono- and bi-nuclear platinum(II) complexes. Platinum(III) complexes of composition [Pt2Cl2(μ-Epy)2(ppy)2] have been isolated with pyE- (E = O or S) ligands. These complexes have been characterized by elemental analysis, NMR (1H, 31P, 195Pt) and absorption spectroscopy. The complexes [Pt2(μ-N∩N)2(ppy)2] (N∩N = pyrazole and 3,5-dimethylpyrazole); [Pt(S∩S)(ppy)] (S∩S = ethylxanthate and diisopropyldithiophosphate); [Pt2Cl2(μ-Epy)2(ppy)2] (Epy = 2-pyridinol {Opy} and 2-mercaptopyridine {Spy}) and [PtCl(ppy)(PhNC(Me)NHPh)] have been structurally characterized by X-ray crystallography.
