New supramolecular adducts of cucurbit[6]uril with triangular cluster chloroaquacomplexes of Mo and W with mixed sulfido-selenido bridging ligands, {[W3S3Se(H2O)(7)Cl-2](2)(C36H36N24O12)}Cl-2 center dot 15H(2)O (1), {[W3S1.5Se2.5Cl1.5(H2O)(7.5)](2)(C36H36N24O12)}Cl-5 center dot 18.5H(2)O (2), and {[Mo3SSe3(H2O)(7.5)Cl-1.5](2)x (C36H36N24O12)}C-l5 center dot 11H(2)O (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.
