Abstract

The following adducts of cucurbit[6]uril and cucurbit[8]uril with triangular cluster chloroaquacomplexes have been prepared and characterized: {[Mo3S4(H2O)7Cl2]2(CB[6])}Cl4·13H2O (I), (H3O)2{[Mo3Se4×(H2O)6Cl3](CB[6])}Cl3·3.5H2O (II) and (H3O)2{[Mo3S4(H2O)4Cl5](CB[8])}Cl·14H2O (III). It is shown that the formation of complementary hydrogen bonds in the systems cucurbit[6]uril/[M3Q4(H2O)9−xClx](4−x)+ (x = 1–3) results in a selective isolation of isomers containing chlorine atom in the trans-position to the capping μ3-ligand. For large x, a selective inclusion of one or another form into the supramolecular compound is also affected by other factors (a system of hydrogen bonds, S⋯S and S…Cl interactions between cluster complexes, packing effects etc.).
