Synthesis, crystal structure and photophysical properties of chlorido­[2-(2′,6′-di­fluoro-2,3′-bipyri­din-6-yl-κN1)-6-(pyridin-2-yl­­oxy-κN)phenyl-κC1]platinum(II)

The title compound, [Pt(C21H12F2N3O)Cl], crystallizes with two crystallographically independent mol­ecules (A and B) in the asymmetric unit, which adopt similar conformations. The PtII atoms in both mol­ecules adopt distorted square-planar geometries, coordinated by one C and two N atoms from the tridentate 2′,6′-di­fluoro-6-[3-(pyridin-2-yl­oxy)phen­yl]-2,3′-bi­pyridine ligand and a chloride anion: the C and Cl atoms are trans. In the crystal, C—H⋯Cl/F hydrogen bonds, F⋯π and weak π–π stacking inter­actions between adjacent A and B mol­ecules and between pairs of inversion-related B mol­ecules lead to the formation of a two-dimensional supra­molecular network lying parallel to the ab plane. The sheets are stacked along the c-axis direction and linked by F⋯π and weak π–π stacking inter­actions between pairs of inversion-related A mol­ecules, forming a three-dimensional supra­molecular network. The photoluminescence quantum efficiency of the title compound in the blue–green region of the visible region (λmax = 517 and 544 nm) is estimated to be ∼0.2–0.3, indicating that the title compound could be a suitable candidate as the emitting material in organic light-emitting diode (OLED) applications.
