Enantiomer Separation of Tris(2,2′-bipyridine)ruthenium(II): Interaction of a D3-Symmetric Cation with a C2-Symmetric Anion
A compound widely used in the separation of the enantiomers of Δ,Λ-[Ru(bipy)3]2+ (bipy = 2,2′-bipyridine) and originally described as “a curious lattice compound” with the formula Δ-[Ru(bipy)3]3[Sb2(R,R-tart)2]2I2·18H2O (tart = tetradeprotonated, carboxyl and hydroxyl, tartaric acid anion) has been crystallographically characterized as this species with a slightly higher degree of hydration (19.5H2O). The crystal lattice has a layered structure in which sheets containing Δ-[Ru(bipy)3]2+ cations and iodide anions alternate with those containing [Sb2(R,R-tart)2]2– anions and water. The role of the iodide ions, which lie in pseudohexagonal cavities formed by the array of three inequivalent but…
