The Reaction of [CP2+NB2(B2H6)2] (CP+ = ETA-ETME4C5) with Sulfur: Stabilization of the Tetrathioborato Ligand in Novel Sulfido Niobium Clusters

Zusammenfassung

An equilateral Nb3 triangle the edges of which are spanned by a BS4 tetrahedron and bridged by sulfido ligands on the ``underside'' is found in cluster 1. The synthesis of this cluster with an unusual electron configuration shows that tetrathioborates can serve as ligands in organometallic chemistry. Cp+ = eta-5-EtMe4C5.
