Synthesis and Crystal Structure of Cucurbit[6]uril Adduct of Hydrogen-bonded Cluster Complex [Mo3(μ3-Se)(μ2-O)3(H2O)6Cl3]+

摘要

Reaction of [MoOCl5]2− with in situ generated H2Se under hydrothermal conditions (4M HCl, 140 °C) leads to reduction of Mo(V) to Mo(IV) with the formation of a triangular cluster Mo3(μ3-Se)(μ-O) 3 4+ in high yield. It is present in HCl solutions as aqua chlorocomplex [Mo3(μ3-Se)(μ-O)3(H2O)6Cl3]+ which was isolated and structurally characterized as supramolecular adduct with cucurbit[6]uril (CB[6]), {[Mo3(μ3-Se)(μ-O)3(H2O)6Cl3]2CB[6]}Cl2·15H2O.
