Abstract

Assembly of 2-phenylquinoline-4-carboxylic acid and Cd(CH3COO)2 · 2H2O or CdSO4 · 8H2O gave two new complexes [Cd2(pqc)4(phen)2(H2O)2] · 2H2O (1) and {[Cd(pqc)2(bpy)(H2O)2] · 2H2O} n (2) (pqcH = 2-phenylquinoline-4-carboxylic acid, phen = 1,10-phenanthroline, bpy = 4,4′-bpy). Complexes 1 and 2 have been characterized by single-crystal X-ray diffraction, IR, powder X-ray diffraction, thermogravimetric analyses, and fluorescence spectra. Structural analyses reveal that 1 is binuclear; the binuclear Cd(II) units are linked by intermolecular hydrogen bonds and π–π interactions to generate a supramolecular structure. Complex 2 possesses a 1-D infinite chain with chains further assembled into a 3-D supramolecular network by π–π, H-bonding, and C–H ··· π interactions.
