Abstract

Solvothermal reaction of Ti(OiPr)₄ with CoBr₂ in ⁱPrOH at 150 °C gives the ion-separated compound [Ti₁₂O₁₅(OⁱPr)₁₇]⁺[(BrCo)₆Ti₁₅O₂₄(OⁱPr)₁₈(Br)]⁻, the heterometallic Ti₁₅Co₆ anion of which contains a Br⁻ ion trapped within a polyoxotitanate shell. This arrangement provides evidence of new host–guest chemistry in this area.
