Effect of fluorosubstitution in the ligand on structure, spectral and thermal characteristics of trimethylplatinum β-diketonate complexes

•The crystal packing of Me3Pt(L)Py molecules is sensitive to F content in the ligand.•The π...π interactions appeared in the structures of fluorinated complexes.•Molecule deformation in the crystals of complexes may affect their volatility.•Fluorinated complexes exhibit high volatility and stability up to melting.
