Synthesis, crystal structure, and properties of a double-helical zinc(II) coordination polymer with Ozagrel drug

By the reaction of Zn(OAc)2·2H2O with Ozagrel, (E)-3-(4-((1H-imidazol-1-yl)methyl)phenyl)acrylic acid (Himpaa), a novel coordination polymer [Zn(impaa)2]n(1) was synthesized and was characterized by IR, elemental analysis, single-crystal X-ray diffraction analysis, photoluminescence spectroscopy, and thermogravimetric and differential thermal analysis. The four-coordinate Zn(II) ions are linked into 1D double-helical chain by the deprotonated impaa−, which is extended into a 3D supramolecular structure through intermolecular C–H⋯O hydrogen bonds.

A novel coordination polymer [Zn(imppa)2]n {Himppa = (E)-3-(4-((1H-imidazol-1-yl)methyl)phenyl)acrylic acid} contains double-helical chains that are extended into a 3D supramolecular structure through intermolecular C–H⋯O hydrogen bonds.Figure optionsDownload as PowerPoint slideHighlights
