Crystal structures of the Ti(III) tweezer complexes [(C5HMe4)2Ti(σ-C≡CSiMe3)2]-[Li(THF)2]+ (2a), [(C5HMe4)2Ti(σ-C≡CSiMe3)2]-Na+ (3) and [(C5HMe4)2Ti(σ-C≡CSiMe3)2]-Cs+ (5) have been determined. In all of them the alkali metal cation is placed away from the Ti-Cα1-Cα2 plane at the distance: Li+ 0.511 Å, Na+ 1.023 Å and Cs+ 0.521 Å. The reason for the deviation of Li+ in 2a is the asymmetrical orientation of the THF ligands in the [Li(THF)2]+ cation with respect to the Ti-Cα1-Cα2 plane, which seems to release the steric congestion between the THF ligands and the trimethylsilyl groups. In 3 and 5, the molecules form polymer chains with a weak intermolecular bonding interaction between the cations and one of the C5HMe4 ligands of the neighbouring molecule in a sandwich manner.

A preparative study of chloro and bromo complexes of tri- and tetra-valent ruthenium has shown that the principal ruthenium(III) chloro species, isolated with alkali metal cations from HCl solution, are [RuCl6]3- and [RuCl5H2O]2-. But in the case of the ruthenium(III) bromo system the only anionic product isolated was [Ru2Br9]3-. The dinuclear anion was also reversibly oxidized in solution to the ruthenium(IV) species [RuBr6]2-. Structural studies, by X-ray powder diffraction, have highlighted the close structural similarity of K2 [RuBr6] and K3 [Ru2Br9]. A Ru-Ru bond is proposed for the dinuclear unit. Both X-ray structural and infrared studies have been carried out on the complexes isolated.

Sodium And Potassium

Two-armed lariat ethers having double bonds present in their side arms form stable complexes with sodium and potassium cations. When the double bonds are positioned appropriately, cation-π interactions are observed between the neutral double bonds and the macroring- bound cation as demonstrated by X-ray crystallography.
