Abstract
The title complex 1, {[CuEu(Hbidc)2(H2O) 4].H2O}n (H3bidc = 1H-benzimidazole- 5,6-dicarboxylic acid), has been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Complex 1 crystallizes in triclinic, space group P1, with a = 7.791(2), b = 12.058(3), c = 12.109(3) Å, α = 82.189(5), β = 72.407(5), γ = 89.184(4)̊, V = 1073.7(5) Å3, C18H 18CuEuN4O13, Mr = 713.86, Dc = 2.208 g/cm3, μ(MoKa) = 3.967 mm-1, F(000) = 700, GOOF = 0.950, Z = 2, the final R = 0.0531 and wR = 0.1068 for I > 2σ(I). Complex 1 possess a tape-like chain structure consisting of Eu2C8O4 and Cu2Eu2C18N4O4 metallic rings alternatively arranged and is the first 3d-4f heterometallic complex based on the 1H-benzimidazole- 5,6-dicarboxylato ligand (Hbidc). Plenty of hydrogen-bonding and π...π stacking interactions connect the 1D chains to construct a 3D supramolecular architecture.
