Assembly and packing models of Ti_(6)Co_(12) ring based on the titanium-capped cobalt clathrochelates

摘要

In this work,titanium-capped cobalt clathrochelates have been applied as secondary building units(SBUs) fo r the construction of supramolecular rings.Two heterometallic wheel-like [Ti_(6) Co_(12)] complexes based on cobalt clathrochelates,[C_(6)H_(15)N_(4)]_(2)[TiCo_(2)(μ_(2)-Oipr)(Oipr)_(2)(Dmg)_(3)]_(6)(2,Dmg=dimethy[glyoxime) and H_(6)[TiCo_(2)(μ_(2)-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.
