Abstract

The crystal structure of the Re(CO)₃(H₂O) ₃⁺ cation has been determined from crystals obtained by evaporation of an aqueous solution of [Re(CO)₃(H₂O) ₃]Br. The bromide ion is incorporated in the Re₂(CO) ₉(μ₃-Br)₃^- anion. A second structure was obtained by removal of bromide as AgBr and precipitation of the Re(CO)₃(H₂O)₃⁺ cation with PF ₆^-. In the latter structure the conjugate base, Re(CO)₃(OH)(H₂O)₂ is cocrystallized in the structure. Each structure along with the previously known cubane [Re(CO) ₃(μ₃-OH)]₄·4H₂O was obtained multiple times during crystallization studies. The use of other anions to generate crystalline products was unsuccessful.
