A new trans-bisalkynyl complex of Pt(II) is synthesized. It contains alkynyl ligands with the diphenylphosphoryl group and additional triphenylphosphine ligands. The composition and structure of the obtained complex are determined by high-resolution mass spectroscopy, polynuclear NMR and IR spectroscopy techniques. The molecular structure of the complex is determined by the single crystal X-ray diffraction analysis. The obtained complex is not found to demonstrate photoluminescence, which can be explained by the atypical composition and energy of electronic transitions described based on the quantum chemical computations.
