One-dimensional void-space arrays constructed from a coordination polymer with bowl-like frameworks of cavitands

A one-dimensional coordination polymer of [MnII(hfac)2] bridged by new bowl-like ligands of cavitands was prepared and the crystal structure was determined by X-ray crystal analysis. Ethyl acetate molecules are necessarily included as guest molecules in each of the void-space cavities of the cavitands, and then are held by weak interaction forces.
