A new 2-D cobalt coordination polymer with the flexible 2-(1<i>H</i>-imidazole-1-yl)acetate: synthesis, structure, and characterization

Abstract

Abstract A new cobalt coordination polymer with linking unit 2-(1H-imidazole-1-yl)acetate (ima), [Co(ima)2] n (1), has been synthesized and structurally characterized by elemental analysis, IR spectra, and X-ray single-crystal diffraction. The X-ray analysis indicates that a neutral 2-D coordination polymer with (3,6) topology was obtained, which shows a 3-D supramolecular network through C–H···O weak interactions. Complex 1 displays mild antimicrobial activity against Achromobacter xylosoxidans ATCC 2706, Bacillus subtilis ATCC 6633, and Candida albicans ATCC 90028, respectively. The magnetic and thermal gravimetric properties for 1 have been investigated and discussed.
