Abstract: In each of the zinc(II) complexes bis(acetylacetonato-![[kappa]](/logos/entities/kappa_rmgif.gif)
2O,O')(1,10-phenanthroline-2N,N')zinc(II), [Zn(C5H7O2)2(C12H8N2)], (I), and bis(acetylacetonato-2O,O')(2,2'-bipyridine-2N,N')zinc(II), [Zn(C5H7O2)2(C10H8N2)], (II), the metal center has a distorted octahedral coordination geometry. Compound (I) has crystallographically imposed twofold symmetry, with Z' = 0.5. The presence of a rigid phenanthroline group precludes intramolecular hydrogen bonding, whereas the rather flexible bipyridyl ligand is twisted to form an intramolecular C-H
O interaction [the chelated bipyridyl ligand is nonplanar, with the pyridyl rings inclined at an angle of 13.4 (1)°]. The two metal complexes are linked by dissimilar C-HO interactions into one-dimensional chains. The present study demonstrates the distinct effects of two commonly used ligands, viz. 1,10-phenanthroline and 2,2'-bipyridine, on the structures of metal complexes and their assembly.
Formula: [Zn(C5H7O2)2(C12H8N2)] and [Zn(C5H7O2)2(C10H8N2)]
