Abstract

Four indole-substituted tridentate iminophosphorane ligands carrying NN’S- and NN’Se-donor atoms, i.e., HL^SMe, HL^SPh, HL^SeMe and HL^SePh, were prepared and combined with [Pt(SMe₂)₂Cl₂] to yield complexes of the compositions [Pt(L^SMe)Cl] (1a), [Pt(L^SPh)Cl] (1b), [Pt(L^SeMe)Cl] (2a) and [Pt(L^SePh)Cl] (2b). Product characterization by elemental analysis, mass spectrometry, NMR spectroscopy (¹H/¹³C/³¹P) and single-crystal X-ray diffraction revealed complexes with metal ions embedded in unsymmetrical square-planar coordination environments and largely planar ligand skeletons with extensive π-delocalization. The residual Pt-Cl bond and multiple options for ligand structure modification make this Pt(II) complex class promising for the future development of catalytic and pharmaceutical applications.

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
