[Co(H2O)6]2+and H3O+encapsulated in a unique 3D anionic Co(ii) framework with hydrophilic hexagonal and circular channels

Abstract

An interesting Co-based 3D framework exhibits a rare example where [Co(H₂O)₆]²⁺and H₃O⁺ions not only act as counterions to balance the negatively charged structure, but also may serve as templates in the assembly of the anionic framework with open hydrophilic channels.
