Such protection allows the isolation of relatively stable, molecular compounds with -OH/SH functional groups attached directly to silicon atoms.…”

The silicon–sulfur compound bis‐1,3‐[di(2,6‐diisopropylphenoxy)]disiloxane‐1,3‐dithiol was obtained from silicon disulfide and 2,6‐diisopropylphenol in a reaction catalyzed by imidazole or 4‐(dimethylamino)pyridine (DMAP). The disiloxane‐1,3‐dithiol is produced in a low yield but in a repeatable manner and can be isolated as colorless crystals. The X‐ray crystal structure of the compound reveals a linear or close‐to‐linear Si–O–Si angle and a mutual trans position of the two hydrosulfido groups. The compound forms a chelating mononuclear complex with cadmium ions. In the complex, the sulfido groups adopt a cis conformation, and the Si–O–Siangle deviates from linearity. The molecular structure of the compound is discussed on the basis of DFT calculations.

Four heteroleptic complexes of nickel(ii), cobalt(ii) and zinc(ii), containing a monodentate silanethiolate ligand derived from tris(2,6-diisopropylphenoxy)silanethiol (TDST), were prepared and characterized. Nickel(ii) and cobalt(ii) complexes of the formula M(NH3)2(TDST)2 (M = Ni(ii) complex , M = Co(ii) complex ) were obtained from the respective chlorides. Zinc complexes of the general formula Zn(acac)(TDST)(L), where L = EtOH (complex ) or H2O (complex ), were obtained from zinc acetylacetonate. A single-crystal X-ray structural analysis revealed that all crystalline products are solvent adducts. The geometries of ligands in the complexes are typical: distorted tetrahedral in zinc and cobalt(ii) complexes and square planar in nickel(ii) compounds. Magnetic studies performed for Ni(ii) and Co(ii) compounds confirmed the diamagnetic character of the first complex and high-spin paramagnetic configuration of the latter. Nickel(ii) and cobalt(ii) complexes were additionally characterized by UV-Vis and IR spectroscopy. IR bands for ligands in the complexes were assigned with the help of the DFT vibrational frequency calculations.

Cation–π interactions involving alkali metal cations are ubiquitous in modern chemical research, impacting everything from the structure of proteins to the activity of catalysis. Here, we survey the role of cation–π interactions involving alkali metal cations in chemistry, biology, and materials science, focusing on their structural and functional significance as well as means by which the strength of these noncovalent interactions can be tuned. In the process, we discuss recent advances in our understanding of the nature of these interactions through applications of spectroscopy and computational chemistry.
