Using the ligand bis(3-(1H-imidazol-1-yl)-1-phenylpropan-1-one) L, two novel com- plexes [CuL2(ph))]·H2O 1 and [ZnL2(tp)] 2 (ph = phthalic acid, tp = terephthalic acid) have been synthesized and their crystal structures were determined by single-crystal X-ray diffraction analysis. Crystal data for 1: triclinic, space group P1, a = 9.4300(17), b = 12.148(2), c = 13.721(2) , α = 109.620(2), β = 94.351(2), γ = 94.830(2)°, C32H30N4O7Cu, Mr = 646.14, V = 1466.2(4) 3, Z = 2, Dc = 1.464 g/cm3, μ(MoKα) = 0.801 mm-1, F(000) = 670, the final R = 0.0337 and wR = 0.0859 for 5122 observed reflections with I > 2σ(I). And those for 2: monoclinic, space group P2/n, a = 7.1866(11), b = 14.144(2), c = 14.407(2) , β = 101.427(2)°, C32H28N4O6Zn, Mr = 629.95, V = 1435.4(4) 3, Z = 2, Dc = 1.457 g/cm3, μ(MoKα) = 0.908 mm-1, F(000) = 652, the final R = 0.0438 and wR = 0.0821 for 2546 observed reflections with I > 2σ(I). In 1 and 2, ph or tp ligands bridge the six-coordinated copper(II) or four-coordinated zinc(II) ions forming 1D zigzag chains while L ligands act as the terminal monodentate ligand. It is noted that weak non-classical C–H···O plays the important and dominating roles in the formation of 2D supramolecular architectures of 1, but in 2 non-classical C–H···O and aromatic π-π stacking interactions are quite important and play dominant roles in the self-assembly of 2D supramolecular architectures.
