Identification and molecular structure of the eighteen-vertex macropolyhedral diplatinaoctadecaborane [(PMe2Ph)2Pt2B16H15(C6H4Me)(PMe2Ph)]

Abstract

The cluster structure of the novel conjuncto macropolyhedral species [(PMe₂Ph)₂Pt₂B₁₆H₁₅(C₆H₄Me)(PMe₂Ph)], isolated in low yield from the brief thermolysis of [(PMe₂Ph)₂PtB₈H₁₂] in boiling toluene, consists of a closo-{Pt₂B₁₀} subcluster and a nido-{Pt₂B₇} subcluster fused via a common {Pt₂B} closed triangular face; a p-tolyl residue, originating from the solvent, is bound to the {Pt₂B₁₀} subcluster.
