Crystal structure of [2,6-difluoro-3-(pyridin-2-yl-κN) pyridin-4-yl-κC4](pentane-2,4-dionato-κ2O,O′)-platinum(II)

초록

The asymmetric unit of the title compound, [Pt(C<inf>10</inf>H<inf>5</inf>F<inf>2</inf>N<inf>2</inf>)(C<inf>5</inf>H<inf>7</inf>O<inf>2</inf>)], comprises one PtII atom, one 2,6-difluoro-2,3-bipyridine ligand and one acetylacetonate anion. The PtII atom adopts a distorted square-planar coordination geometry, being C,N-chelated by the 2,6-difluoro-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 bipyridine ligand are approximately coplanar, making a dihedral angle of 1.2 (2)°. A variety of intra- and intermolecular C - H⋯O and C - H⋯F hydrogen bonds, as well as π-π interactions [centroid-centroid distances = 4.337 (3) and 3.774 (3) Å] contribute to the stabilization of the molecular and crystal structures, and result in the formation of a three-dimensional supramolecular framework.
