Jm. Dou et al., A CLOSO-12-VERTEX DINICKELABORANE - [(ETA(5)-C5H5)(2)NI2B10H10], Acta crystallographica. Section C, Crystal structure communications, 54, 1998, pp. 1418-1419
In the title compound, cyclopentadienyl-1,2-dinickela-closo-dodecabora
ne, [Ni-2(B10H10)(C5H5)(2)], the cluster has a close-twelve-vertex ico
sahedral {Ni2B10} framework. The Ni atoms occupy adjacent vertices of
the polyhedron and each Ni atom is coordinated by a eta(5)-cyclopentad
ienyl ring.
