28. 3, R(F) = 10.24% for 8503 observed independent reflections (4° ≤ 2θ ≤ 56°). There are two solvate molecules of acetone in the asymmetric unit. All non-hydrogen nondisordered atoms were refined anisotropically. Disordered atoms F(2), F(3), and F(7) of two counterions and atoms C(51) and C(53) of an acetone molecule were refined isotropically. Hydrogen atoms were treated as idealized contributions.
