| Abstract: | The inclusion compound of macrocyclic cavitand cucurbit8]uril (CB8]) with the nickel(II) complex containing the tetraazamacrocyclic ligand cyclam, {Ni(cyclam)]@CB8]}Cl2··16H2O (1), and the inclusion compounds of CB8] with the copper(II) bis-ethylene-diamine complex, {trans-Cu(en)2(H2O)2]@CB8]}Cl2·{CB8]}·42H2O (2a) and {trans-Cu(en)2(H2O)2]@CB8]}Cl2·17H2O (2b), were synthesized and characterized by X-ray diffraction analysis, IR and ESR spectroscopy, and electrospray mass spectrometry. Guest—host inclusion compounds can be directly synthesized starting from a metal complex and cucurbit8]uril, as was exemplified by the preparation of compounds 2a and 2b.__________Published in Russian in Izvestiya Akademii Nauk.
