In each of the zinc(II) complexes bis(acetylacetonato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)zinc(II), [Zn(C5H7O2)2(C12H8N2)], (I), and bis(acetylacetonato‐κ2O,O′)(2,2′‐bipyridine‐κ2N,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—H...O 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.
