Macropolyhedral boron-containing cluster chemistry. Novel intercluster linkages from the reaction of [Pt(cod)Cl2] and [PtMe2(PMe2Ph)2] with 6,6′-(B10H13)2O

Abstract

6,6′-(B₁₀H₁₃)₂O with [Pt(cod)Cl₂] gives the [(B₁₀H₁₃OB₁₀H₁₁)Pt–{(B₁₀H₁₀OB₁₀H₁₂)]²⁻ anion in which, uniquely, the units are held together by a B–O–B linkage in combination with a B–B linkage; with [PtMe₂(PMe₂Ph)₂] it gives [(PMe₂Ph)₂PtB₁₀H₁₀–O,H–B₁₀H₁₁Pt(PMe₂Ph)] in which, uniquely, the units are held together by an unsupported hydrogen-to-metal linkage as well as a B–O–B linkage.
