• A new hexa-coordinated zinc(II) complex, namely [ZnL(H2O)2]n, with N2O2 coordination sphere has been synthesized and structurally characterized structurally. The zinc(II) complex exhibits a slightly distorted octahedral geometry with halogen-substituted Salen-type bisoxime forming the basal N2O2 coordination sphere and two oxygen atoms from two coordinated water molecules in the axial position. The hydrogen-bonding and π–π stacking interactions have stabilized the zinc(II) complex molecules to form a self-assembling infinite dual metal–water chain-like structure with the nearest Zn⋯Zn distance of 4.954(4)Å. •A halogen-substituted Salen-type bisoxime has been synthesized firstly.•A new complex [ZnL(H2O)2]n has been synthesized and characterized structurally.•The complex forms a self-assembling infinite dual metal–water chain-like structure.•Some new results are very important to coordination and supramolecular chemistry. A new hexa-coordinated zinc(II) complex, namely [ZnL(H2O)2]n, with N2O2 coordination sphere (H2L=4,4′-dibromo-6,6′-dichloro-2,2′-[ethylenedioxybis(nitrilomethylidyne)]diphenol) has been synthesized and structurally characterized by elemental analyses, IR, UV–vis spectra and TG-DTA analyses, etc. Crystallographic data are monoclinic, space group P21/c, a=24.634(2)Å, b=10.144(1)Å, c=7.9351(6)Å, β=91.371(2)°, V=1982.4(3)Å3, Dc=2.099g/cm3, Z=4. The zinc(II) complex exhibits a slightly distorted octahedral geometry with halogen-substituted Salen-type bisoxime forming the basal N2O2 coordination sphere and two oxygen atoms from two coordinated water molecules in the axial position. The hydrogen-bonding and π–π stacking interactions have stabilized the zinc(II) complex molecules to form a self-assembling infinite dual metal–water chain-like structure with the nearest Zn⋯Zn distance of 4.954(4)Å.
