Abstract
A novel helical-chain coordination polymer [Co(tau)2(4,4′-bipy)]n·nH2O 1 (tau = taurine, 4,4′-bipy = 4,4′-bipyridine) has been hydrothermally synthesized and characterized by infrared spectroscopy, and thermogravimetric analysis, magnetic measurements, solid-state CD spectra and single crystal X-ray diffraction analysis. The intertwist trigonal-fold helical chains are further connected through hydrogen bonds to give a three-dimensional supramolecular network, in which trigonal microporous channels filled with water guest molecules exist within the polymer coils. Compound 1 shows weak antiferromagnetic interactions among metal ions.
