| Abstract: | In this work, titanium-capped cobalt clathrochelates have been applied as secondary building units (SBUs) for the construction of supramolecular rings. Two heterometallic wheel-like Ti6Co12] complexes based on cobalt clathrochelates, C6H15N4]2TiCo2(μ2-Oipr)(Oipr)2(Dmg)3]6 (2, Dmg = dimethylglyoxime) and H6TiCo2(μ2-Oipr)(Oipr)2(Dmg)3]6 (3), have been successfully synthesized and characterized. The supramolecular stacking modes of these wheels are largely dependent on the applied synthetic conditions, which further impact their gas adsorption properties. |
