Popis: Inclusion compounds of the macrocyclic cavitand cucurbit[8]uril (CB[8]) with the ruthenium(iii) bis(ethylenediamine) complex {trans-[Ru(en)2Cl2]@CB[8]}Cl·27.5H2O (1), the gold(iii) diethylenetriamine complex {[Au(dien)Cl]@CB[8]}Cl2·11H2O (2), and the gold(iii) and platinum(ii) cyclam complexes (H3O)5{[Au(cyclam)]@CB[8]}Cl8·18H2O (3) and {[Pt(cyclam)]0.11(H2cyclam)0.89@CB[8]}Cl2·16H2O (4), respectively, where cyclam is the tetraazamacrocyclic ligand, were synthesized. The inclusion compounds were synthesized both directly starting from CB[8] and the metal complexes with polyamines (en or dien) and by the two-step method with the use of the cyclic polyamine ligand (cyclam) pre-included into the cavity of the macrocycle. The inclusion compounds were characterized by X-ray diffraction (1, 2, and 4), IR spectroscopy, electrospray ionization mass spectrometry, UV-Vis spectroscopy, and thermogravimetric analysis.
