—Four cobalt complexes with cucurbit[6]uril (CB[6]), [Co(H2O)6](Bdc)·CB[6]·14.5H2O (I), 2(H2NMe2)2[CoCl4]·CB[6]·12H2O (II), [{Co(H2O)4Cl}4(CB[6])]Cl4·9H2O (III), and [Co(H2O)6]-[Co(H2O)5(Dmf)][CoCl4]2·CB[6]·6H2O (IV), were prepared by evaporation of the reaction solution containing cobalt chloride and cucurbit[6]uril (CB[6]). According to X-ray diffraction data, compound I is formed by packing of cationic cobalt aqua complexes, terephthalate anions, and CB[6] molecules linked together by hydrogen bonds with crystallization water molecules into a supramolecular cage. The structure of compound II represents a packing of CB[6] molecules, dimethylammonium cations, and anionic cobalt chloro complexes. Compound III contains tetranuclear cationic cobalt chloro aqua complexes with CB[6], with chloride anions acting as counter-ions. The crystal structure of IV is a packing of cationic cobalt aqua complexes, anionic cobalt chloro complexes, and CB[6] molecules linked by hydrogen bonds with crystallization water molecules into a supramolecular cage. The resulting compounds are characterized by IR spectra and elemental analysis data.
