3-(4-Hydroxyphenyl)-1,5-bis(pyridin-2-yl)pentane-1,5-dione
In the title mol-ecule, C21H18N2O3, the pyridine rings make a dihedral angle of 13.1 (1)°. The phenyl ring is approximately perpendicular to both of them, forming dihedral angles of 87.4 (1)and 81.9 (1)°. In the crystal, pairs of O-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers. Additional C-H⋯O, π-π [centroid-centroid distance = 3.971 (2) Å] and C-H⋯π inter-actions consolid...

The title mol-ecule, [Ir(C14H14FN2O)2(C5H7O2)], is located on a twofold rotation axis, which passes through the Ir(III) atom and the central C atom of the pentane-2,4-dionate anion. The Ir(III) atom adopts a distorted octa-hedral coordination geometry, being C,N-chelated by two 2-tert-but-oxy-6-fluoro-3-(pyridin-2-yl)pyridin-4-yl ligands and O,O'-chelated by the pentane-2,4-dionato ligand. The ...

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 th...

In the title racemic compound, C12H10ClNO, the dihedral angle between the benzene and pyridine rings is 74.34 (6)°. In the crystal, the mol-ecules are linked by O-H⋯N hydrogen bonds, forming zigzag C(5) [001] chains in which alternating R- and S-configuration mol-ecules are related by c-glide symmetry. In addition, inversion-related pairs of mol-ecules are linked into dimers by pairs of weak C-...
