| Abstract: | Inclusion compounds of the macrocyclic cavitand cucurbit8]uril (CB8], C48H48N32O16) with the copper(ii) and zinc(ii) complexes with the tetraazamacrocyclic ligand cyclam, {Cu(cyclam)(H2O)2]@CB8]}Cl2·18H2O (1) and {Zn(cyclam)]@CB8]}Cl2·13H2O (2), were synthesized. The compounds were characterized by X-ray diffraction analysis, electrospray mass spectrometry, IR spectroscopy,
and elemental analysis. The 1H and 13C NMR method revealed only one trans-isomer of the zinc(ii) complex with cyclam in an aqueous solution of inclusion compound 2. |
