A new complex [Zn2(Ox)3]H2L · 4H2O (L = 2,2′-(1,4-butanediyl)-bis(1H-benzimidazole)) (I) has been hydrothermally synthesized and characterized by the elemental analysis, IR spectroscopy, and single crystal X-ray diffraction. It crystallizes in monoclinic space group P21/c with a = 10.108(2), b = 15.600(4), c = 9.768(2) Å, β = 105.289(3)·, V = 1485.7(6) Å3, Z = 4. Complex I is a 2D honeycomb-like polymer with pro-toned L and water molecules intercalating in the cavities. The luminescent spectra shows the emission peak of complex I is at 455 nm which is attributed to ligand-to-metal charge transfer.
