Complexes of silanethiolate ligands: Synthesis, structure, properties and application

Solvent influence on the crystal structures of new cadmium tri-tert-butoxysilanethiolate complexes with 1,4-bis(3-aminopropyl)piperazine: luminescence and antifungal activity

“…The number of bands occurring in this range for compound 2 is greater than for complex 1. The bands observed in the range 1100-980 cm À 1 for both complexes are characteristic for the Si-O-C bonding present in the (tBuO) 3 SiS À residues, and their patterns are typical for silanethiolate residues coordinating to metallic centres as terminal S-donor residues (Pladzyk et al, 2021).…”

“…Our scientific group is investigating alkoxy-and aryloxysilanethiols, (RO) 3 SiSH, which are analogues of organic thiols, RSH. They contain a C-O-Si-S-H moiety instead of a C-S bond and act as both S-terminal and O,S-chelating ligands in the synthesis of coordination compounds (Pladzyk et al, 2021). The compound commonly used by us in the syntheses of silanethiolates is tri-tert-butoxysilanethiol, (tBuO) 3 SiSH (TBST).…”

“…Due to its spatial structure, it shows remarkable resistance towards hydrolysis of the Si-S bonds, allowing for synthesis under atmospheric conditions, giving mono-, di-or polymeric complexes of various metals. Our research focuses on the design and preparation of heteroleptic metal silanethiolates that exhibit luminescence, magnetic and/ or catalytic features (Pladzyk et al, 2021). One group of such derivatives is cadmium silanethiolates and our current research is directed towards recognizing the role of 1,4-bis(3aminopropyl)piperazine (BAPP) in the structural, spectral and cytotoxic properties of cadmium tri-tert-butoxysilanethiolates containing this ligand.…”

Salts of Tris(pentafluoroethyl)silylchalcogenolates [Si(C2F5)3E]− with E = S, Se, and Te: Synthesis, Structure, and Reactivity

“…Alkali-metal chalcogenolates M[SiR 3 E] (M = alkali metal) are generally prepared by deprotonation of the corresponding chalcogenols, SiR 3 EH, 3−6 or by cleavage of the Si−E bonds in bis-silylated chalcogenides, for example. 5,7−11 Here, mainly the thiolates 3,5,7 were considered in more detail, while the chemistry of the corresponding selenolates 12 and tellurolates 13 remained underdeveloped. 14 Recently, Sundermeyer et al described the syntheses of monomeric N,N-dimethylpyrrolidinium chalcogenolates [Me 2 Pyr][SiMe 3 E] with E = S, Se, and Te.…”

“…Over the years, the heavier congeners of silylchalcogenolates [SiR 3 E] − (R = alkyl, aryl; E = S, Se, Te), which in the following will be addressed as chalcogenolates only, have also moved into the focus of interest, and various methods have been devised for their synthesis. Alkali-metal chalcogenolates M­[SiR 3 E] (M = alkali metal) are generally prepared by deprotonation of the corresponding chalcogenols, SiR 3 EH, − or by cleavage of the Si–E bonds in bis-silylated chalcogenides, for example. ,− Here, mainly the thiolates ,, were considered in more detail, while the chemistry of the corresponding selenolates and tellurolates remained underdeveloped .
