Synthesis, crystal structure and photophysical properties of chlorido-[2-(2',6'-di-fluoro-2,3'-bipyri-din-6-yl-?N 1)-6-(pyridin-2-yl-oxy-?N)phenyl-?C 1]platinum(II).

ABSTRACT: The title compound, [Pt(C21H12F2N3O)Cl], crystallizes with two crystallographically independent mol-ecules (A and B) in the asymmetric unit, which adopt similar conformations. The PtII atoms in both mol-ecules adopt distorted square-planar geometries, coordinated by one C and two N atoms from the tridentate 2',6'-di-fluoro-6-[3-(pyridin-2-yl-oxy)phen-yl]-2,3'-bi-pyridine ligand and a chloride anion: the C and Cl atoms are trans. In the crystal, C-H?Cl/F hydrogen bonds, F?? and weak ?-? stacking inter-actions between adjacent A and B mol-ecules and between pairs of inversion-related B mol-ecules lead to the formation of a two-dimensional supra-molecular network lying parallel to the ab plane. The sheets are stacked along the c-axis direction and linked by F?? and weak ?-? stacking inter-actions between pairs of inversion-related A mol-ecules, forming a three-dimensional supra-molecular network. The photoluminescence quantum efficiency of the title compound in the blue-green region of the visible region (?max = 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.
