Popis: Assembly of 2-phenylquinoline-4-carboxylic acid and Zn(OAC)2·2H2O gives rise to two complexes [Zn2(C16H10NO2)4 (phen)2(H2O)2]·2H2O (I) and [Zn2(C16H10NO2)4(bpy)2]n (II) (phen = 1,10-phenanthroline, bpy = 4,4′-bipyridine). Complexes I and II have been characterized by x-ray single-crystal diffraction, infrared (IR), powder x-ray diffraction (PXRD), thermogravimetric analysis (TGA), and fluorescence spectra. Structural analysis reveals that I is binuclear in structure; two Zn(II) centers are bridged by two carboxylate groups and the terminal water molecule occupies a axial position of the octahedral geometry, which further extends the binuclear unit into a supramolecular framework via intermolecular hydrogen bonding and π···π interactions. Complex II possesses a one-dimensional infinite zigzag chain architecture by bridging of the 4,4′-bipyridne.
