The thermal behavior and luminescent properties of palladium(II) Pd(L^R)₂ complexes with 3-(2-pyridyl)-5-R-1,2,4-triazoles (L^R , where R = H, Ph, Me) in cristalline state were studied. Analysis of the stationary and time-resolved Pd(L^Me)₂ photoluminescence spectra showed that the introduction of electron–donor methyl substituent into a coordinated ligand is accompanied by emission in the green range of the spectrum (fluorescence, λ_max = 442 nm). Molecule aggregation in Pd(L^H)₂ and Pd(L^Ph)₂ complexes leads to a bathochromic shift of emission (phosphorescence, 𝜆_max = 712 and 691 nm).
