A novel supramolecular adduct formed by CB[6]-based pseudo-rotaxane and hydrated Zn(II) ion

A novel supramolecular adduct of [C6N2(CB[6])]3 · [Zn(H2O)6]Cl2 · 14H2O (1) is reported, where C6N2 = N,N′-bis(2-pyridylmethyl)-1,6-diaminohexane, CB[6] = Cucurbit[6]uril. It consists of a CB[6]-based pseudo-rotaxane and a six-hydrated Zn(II) ion, and forms an infinite 2D network and 3D spatial structure by hydrogen bonding interactions.
