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 P2(1)/c, a=24.634(2)Å, b=10.144(1)Å, c=7.9351(6)Å, β=91.371(2)°, V=1982.4(3)Å(3), Dc=2.099 g/cm(3), 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.
一种新的六配位锌（II）配合物，即[ZnL（H2O）2]n，具有 N2O2 配位球（H2L=4,4'-二溴-6,6'-二氯-2,2'-[乙二氧基双（亚氨基甲基）]二苯酚），已通过元素分析、IR、UV-vis 光谱和 TG-DTA 分析等方法合成并进行了结构表征。晶体学数据为单斜晶系，空间群 P2(1)/c，a=24.634(2)Å，b=10.144(1)Å，c=7.9351(6)Å，β=91.371(2)°，V=1982.4(3)Å(3)，Dc=2.099 g/cm(3)，Z=4。锌（II）配合物呈现出略微扭曲的八面体几何形状，卤素取代的Salen 型双肟形成了基底的 N2O2 配位球，两个来自两个配位水分子的氧原子位于轴向位置。氢键和π-π堆积相互作用稳定了锌（II）配合物分子，形成了自组装的无限双金属-水链状结构，最近的 Zn⋯Zn 距离为 4.954(4)Å。
