“…The H bond with Ct C-H alkyne terminal group as a proton donator is an example of such interaction. 10 The C(sp 2 )-H‚‚‚S(sp 3 ) and C(sp 2 )-H‚‚‚N(sp 3 ) intramolecular contacts are analyzed in this paper because they occur within the crystal structures of 3-methyl-2,4-diphenyl-(1,3)-thiazolidine-5-spiro-2′-adamantane (1) and 3-methyl-2,4,5,5-tetraphenyl-(1,3)-thiazolidine (2) investigated here. Compounds 1 and 2 were synthesized within the more extensive studies on derivatives of (1,3)-thiazolidines; [11][12][13] some of these heterocycles may be used in synthesis of immunomodulating drugs or antibiotics.…”

The crystal and molecular structures of 3-methyl-2,4-diphenyl-(1,3)-thiazolidine-5-spiro-2′-adamantane and 3-methyl-2,4,5,5-tetraphenyl-(1,3)-thiazolidine are investigated showing the existence of C(sp 2 )-H‚‚‚S and C(sp 2 )-H‚‚‚N intramolecular contacts. The use of the Bader theory shows that C-H...S interactions existing in crystal structures may be treated as weak H bonds. The C-H...N and C-H...S interactions are also analyzed here for simple modeled complexes of (1,3)-thiazolidine as the proton acceptor and simple proton donators: HF, H 2 O, C 2 H 4 , and C 2 H 2 molecules. The calculations for these complexes were performed within the DFT method, B3LYP/6-311++G** level of theory. The bond critical points (BCPs) were found for these modeled systems and the analysis of the electron densities and their Laplacians at BCPs was performed.

A Convenient Route to Synthetic Analogues of the Oxidized Form of High-Potential Iron–Sulfur Proteins

An amide-bound [Fe4S4](3+) cluster, [Fe4S4{N(SiMe3)2}4](-) (1), was found to serve as a convenient precursor for synthetic analogues of the oxidized form of high-potential iron-sulfur proteins. Treatment of 1 with 4 equiv of bulky thiols led to replacement of the amide ligands with thiolates, giving rise to a series of [Fe4S4(SR)4](-) clusters (R = Dmp (2a), Tbt (2b), Eind (2c), Dxp (2d), Dpp (2e); Dmp = 2,6-di(mesityl)phenyl, Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Eind = 1,1,3,3,5,5,7,7-octaethyl-s-hydrindacen-4-yl, Dxp = 2,6-di(m-xylyl)phenyl, Dpp = 2,6-diphenylphenyl). These clusters were characterized by the mass spectrum, the EPR spectrum, and X-ray crystallography. The redox potentials of the [Fe4S4](3+/2+) couple, -0.82 V (2a), -0.86 V (2b), -0.84 V (2c), -0.74 V (2d), and -0.63 V (2e) vs Ag/Ag(+) in THF, are significantly more negative than that of [Fe4S4(SPh)4](-/2-) (-0.21 V).
