Using two structurally related benzoates bearing different H-bond acceptors as co-ligands, three new azido-CuⅡ compounds, [Cu(L1)(N3)(H2O)]n (1), [Cu(L1)(N3)(MeOH)]n (2), and [CuL2HL2(N3)3(H2O)]n (3) (HL1 = 4-nitrobenzoic acid; HL2 = 2-phenyl-4-quinolinecarboxylic acid), have been synthesized and structurally characterized. 1 is a carboxylate/EO-azido bridged copper chain, forming 3D structure by H-bonds, and 2 has a similar chain structure as 1 but forming a 2D structure by H-bonds, while 3 is a 3D supramolecular network with ternary center H-bonds. Magnetic study indicates that domain ferromagnetic coupling interactions were found to exist in complexes 1 and 3.
