Abstract
New supramolecular adducts of cucurbit[6]uril with triangular cluster chloroaquacomplexes of Mo and W with mixed sulfido-selenido bridging ligands, {[W3S3Se(H2O)7Cl2]2(C36H36N24O12)}Cl2·15H2O (1), {[W3S1.5Se2.5Cl1.5(H2O)7.5]2(C36H36N24O12)}Cl5·18.5H2O (2), and {[Mo3SSe3(H2O)7.5Cl1.5]2×(C36H36N24O12)}Cl5·11H2O (3) are obtained treating the mixture of products in Mo-S-Se-Br and W-S-Se-Br systems, isolated, and structurally characterized. In all compounds, the supramolecular structure is based on hydrogen bonded associates of cucurbit[6]uril molecule with two cluster cations.
