A procedure of synthesis of Pd (II) complexes with 2-phenylquinoline-4-carboxylic acid methyl ester: [PdMpqc(μ-Аc)]2 and [PdEnMpqc] BF4, where Mpqc is methyl 2-phenyl-4-quinolinecarboxylate ion, Ac - acetate ion, En - ethylenediamine, was developed. The composition and structure of the complexes obtained were established on the basis of IR and polynuclear NMR spectroscopy data, optical and physical properties were described on the basis of UV and fluorescence spectroscopy. The phosphorescence of Pd (II) complexes in the visible region was assigned to the radiative transition from the spin-forbidden intraligand electronically excited state 3(π-π) that is localized on the aromatic Mpqc system.
