SYNTHESIS AND CHARACTERIZATION OF TWO NOVEL,NEST-SHAPED Mo-Cu-S CLUSTER COMPOUNDS, [MoOS3Cu3(Py)5X] (X = Br,I), AND THE SUBSTITUTION OF Mo-Cu-S CLUSTERS

Abstract

The title compounds [MoOS₃Cu₃(Py)₅Br] (3) and [MoOS₃Cu₃(Py)₅I] (4) were obtained through the nest-shaped cluster [(n-Bu)₄N]₂[MoOS₃Cu₃BrCl₂] (1) and twin-nest-shaped cluster [Et₄N]₄[Mo₂Cu₆S₆O₂Br₂I₄](2) by reacting with pyridine. They show nest-shaped skeletons, and are characterized structurally by single-crystal X-ray analysis. These are the first neutral nest-shaped Mo(W)-Cu(Ag)-S clusters.
