Synthesis, Crystal Structure, and Characterization of One 1D Complex in Ni2+/H4L/p-Bix System (H4L = Methylenediisophthalic Acid, p-Bix = 1,4-Bis(Imidazol-1-Ylmethyl)-Benzene)

Under hydrothermal condition, one 1D Ni(II) complex has been prepared. The result of X-ray diffraction analysis (CIF file CCDC no. 972293) shows that in this complex both Ni(II) atoms adopt sixcoordinated mode. First, L is coordinated to four Ni(II) atoms to form 1D [(Ni2(L))]∞ (H4L = methylenediisophthalic acid) chain. Then, p-Bix = 1,4-bis(imidazol-1-ylmethyl)-benzene (p-Bix) ligands are decorated alternatively on both sides of 1D [(Ni2(L))]∞ chain to be 1D [(Ni2(L))(p-Bix)]∞ chain. Finally, relying on weak interactions, such as hydrogen bonds and π…π stacking interactions, the complex exhibits 3D supramolecular framework. Moreover, at room temperature, the IR spectrum, PXRD and TG analyses were employed to characterize the complex.
