چکیده
The asymmetric unit of the title compound, [Pt(C10H5F2N2)(C5H7O2)], comprises one Pt(II) atom, one 2,6-di-fluoro-2,3-bi-pyridine ligand and one acetyl-acetonate anion. The Pt(II) atom adopts a distorted square-planar coordination geometry, being C,N-chelated by the 2,6-di-fluoro-3-(pyridin-2-yl)pyridin-4-yl ligand and O,O'-chelated by the pentane-2,4-dionate ligand. The two pyridine rings of the bi-pyridine ligand are approximately coplanar, making a dihedral angle of 1.2 (2)°. A variety of intra- and inter-molecular C-H⋯O and C-H⋯F hydrogen bonds, as well as π-π inter-actions [centroid-centroid distances = 4.337 (3) and 3.774 (3) Å] contribute to the stabilization of the mol-ecular and crystal structures, and result in the formation of a three-dimensional supra-molecular framework.
