elemental analysis, and single crystal X-ray structure analysis. The latter represents the first intermetalloid Ge-Pt cluster with a platinum atom as part of a deltahedron. So far, only one compound of this type has been reported for the homologous Pd. Hence, with these new compounds, metal-coordinated deltahedral Ge9 clusters are now known for the whole triad of group 10 elements. The cluster compounds are

Reaction of [Pt(PEt3)3] with hexakis(trifluoromethyl)benzene affords [PtC6(CF3)6}(PEt3)2], with a 1,2-hapto-structure; reaction of the nickel analogue with more hexafluorobut-2-yne gives a new kind of complex, a nickelahexakis(trifluoromethyl)cyclohepta-cis,trans,cis-triene; both structures have been established by X-ray crystal analysis.

Abstract : Metallocarboranes of iron, cobalt and nickel have been prepared by the direct reaction of the small polyhedral carboranes 1,5-C2B3H5, 1,6-C2B4H6, or 2,4-C2B5H7 with organometallic and metal carbonyl reagents in the gas phase or in solution, without the use of a prior cage-opening step. Novel 6-vertex cages as well as 7-vertex species were obtained, including mono-, di-, and trimetallocarborane
