Summary
Tetraethylammonium 7-dimethylsulfanyl-nido-dodecahydroundecaborate was synthesized by deprotonating a boron cluster. This process caused a contraction in boron-boron distances within the cluster structure.
Area of Science:
- * Inorganic Chemistry
- * Boron Cluster Chemistry
Background:
- * Understanding the reactivity and structural properties of boron clusters is crucial in materials science.
- * Nido-boron clusters offer unique structural motifs and potential applications.
Purpose of the Study:
- * To synthesize and characterize tetraethylammonium 7-dimethylsulfanyl-nido-dodecahydroundecaborate.
- * To investigate the structural consequences of deprotonating the [7-Me(2)S-nido-B(11)H(13)] cluster.
Main Methods:
- * Deprotonation of [7-Me(2)S-nido-B(11)H(13)] using potassium triethylborohydride (KHBEt(3)).
- * Precipitation of the target compound using tetraethylammonium chloride.
Main Results:
- * Successful synthesis of tetraethylammonium 7-dimethylsulfanyl-nido-dodecahydroundecaborate.
- * The removal of an endo-terminal hydrogen atom led to a contraction of the open-face B-B distances in the cluster.
Conclusions:
- * The deprotonation of nido-undecaborate clusters can induce significant structural changes.
- * This study provides insights into the structure-property relationships of functionalized boron clusters.
