Abstract:	The oxonium derivative P(C₆H₅)₄[2-B₁₀H₉O(CH₂)₄] (1) has been prepared from [B₁₀H₁₀]²⁻ by a solvent-addition reaction route, promoted by Et₂O · BF₃. Its structure has been confirmed by single crystal X-ray analysis. 1 is assumed to be a useful synthon for the derivative chemistry of [B₁₀H₁₀]²⁻. As an illustration, ring-opening reaction occurred in presence of the strong nucleophilic agent OH⁻, giving the monoanionic derivative [P(C₆H₅)₄]₂[2-B₁₀H₉O(CH₂)₄OH] (2).
