    Notes: Abstract We studied the ability of the Antarctic fish Notothenia neglecta to conduct an induced inflammatory process at 0°C. Indian ink was injected and a cotton suture thread was implanted into muscle of different groups of fish. After 1–2 days of Indian ink injection, the ink was diffused in the perimysium and there was hemorrhage and cellular infiltrate composed mainly of macrophages A (with few and small lysosomes) and neutrophils; after 7–15 days, there were macrophages A and some macrophages B (cytoplasm clear, lamellar cytoplasmic system forming interdigitations); after 30 days, there was Indian ink in the interior of macrophages A. The suture thread process takes place in two phases: the first (up to 7 days) with predominance of macrophages A and few neutrophils, and the second (15–30 days) with predominance of macrophages B. It can be concluded that N. neglecta is responsive to irritant stimulus with inflammatory process indicating adaptation to the antarctic environment.

    Notes: In the title compound, (2-chlorobenzyl)tris(pyridine-2-thiolato)-κ2N,S;κ2N,S;κS-tin(IV), [Sn(C7H6Cl)(C5H4NS)3], two of the three pyridine-2-thiolato ligands (SPy) are bidentate and one is monodentate. The bonding C atom of the 2-chlorobenzyl group, the S atom of the monodentate SPy and the S and N atoms of the two bidentate SPy ligands form a distorted octahedron around the Sn atom. The three S atoms and the N atom of one of the bidentate SPy ligands occupy the equatorial positions, while the N atom of the second bidentate SPy ligand and the C(CH2) atom are axial. The axial N—Sn—C angle of 157.9 (1)° demonstrates the heavy distortion of the octahedron.

    Notes: Abstract Ethanol solutions of Alk n SnCl4−n (Alk = Me, Et; n = 1–3) added to aqueous calf thymus DNA provoke DNA condensation (even in the presence of added cysteine) possibly through charge neutralization of DNA phosphodiesters by organotin(IV) cations. The structures of tin bonding environments in binary and ternary condensed systems organotin(IV)-DNA and ligand-organotin(IV)-DNA are determined through point-charge model treatment of the 119Sn Mössbauer parameter Δ, while the possible interchain interaction DNA-tin is inferred from the dynamics of 119Sn nuclei through vtMs.

    Notes: The bonding and the configuration of the tin environment in the title compounds {R2Sn[SCH2CH(NH3+)COO-]2 and R2Sn[SC(CH3)2CH(NH3+)COO-]2, indicated in the following as R2Sn(cysH)2 and R2Sn(penH)2 respectively} has been investigated through the determination of the Mössbauer-Zeeman spectra of Ph2Sn(cysH)2 and Ph2Sn(penH)2 in the solid state, and through conventional Mössbauer spectroscopy of Me2Sn(penH)2 in the solid state as well as of Me2Sn(cysH)2 and Me2Sn(penH)2 in aqueous solution (frozen). The treatment of the data by the pointcharge model approach suggested the general occurrence of a tetrahedral C2SnS2 core. In aqueous Hepes buffer, a tertiary amino nitrogen atom has been observed to coordinate tin in Me2Sn(cysH)2 and Me2Sn(penH)2, with formation of trigonal bipyramidal tin environments. The latter solutions undergo slow decomposition reactions at room temperature. From (Me2SnS)3 occurs, as well as formation of soluble complex species in the presence of glycylglycine; Me2Sn(penH)2 appears to undergo a slow desulfuration reaction.

    Synthesis and spectroscopic characterization of R3SnIV derivatives of N-acetyldipeptides (1993)

    Notes: Triorganotin(IV) derivatives of N-acetyldipeptides R3SnAcDip; R=Me, Et, n-Bu, n-Oct, Cy or Ph (HAcDip=N-acetylglycylglycine and N-acetylglycylvaline; R=Me, n-Bu, Cy, HAcDip=N-acetylglycylalanine) were obtained by neutralization of R3SnOH and HAcDip. The complexes were studied by means of 119Sn Mössbauer, IR and 1H, 13C and 119Sn NMR spectroscopy. The C—Sn—C bond angles have been inferred by rationalization of Mössbauer nuclear quadrupole splittings as well as from NMR coupling constants. Correlations of Mössbauer isomer shifts with partial atomic charges on tin atoms have been determined: Polymeric trigonal bipyramidal structures, with near-planar R3Sn units and axial carboxylate (unidentate) and C=O amide donor groups are inferred for all the compounds in the solid state, except for Cy3SnAcGlyVal for which a tetrahedral structure is proposed. In solution the complexes are monomeric; in methanol a solvent molecule is coordinated to tin which then is still in a trigonal bipyramidal environment.

    A 119Sn Mössbauer spectroscopic study on complexes of di-and tri-organotin(IV) moieties with 2-mercaptoethanesulfonates, in the solid state and in aqueous solution (1988)

    Notes: The configuration of the bonding environment of tin in the complexes [R2Sn(SCH2CH2SO3)2]2- (R = Me, Ph) and [Me3Sn(SCH2CH2SO3)]- has been determined to be tetrahedral both in the solid state and in aqueous solution (for the methyl derivatives). The coordination number of tin increases to five in aqueous solutions for the Me2Sn(IV) complexes in Hepes buffer (N-2-hydroxyethylpiperazine-N′-2-ethanesulfonic acid; at least in fivefold excess, at pH 7.4) due to coordination by the tertiary amino nitrogen atom. No effect is detected due to the surfactant 2-hydroxypropylcellulose concerning both coordination to tin and influence on the Mössbauer parameters. The stoichiometry of mixed complex formation in aqueous solution of Me2Sn(IV), 2-mercaptoethanesulfonate and Hepes is 1:2:1, according to a procedure of ‘Mössbauer titration’. All complexes in aqueous solution undergo slow lysis of the tin-sulfur bonds. Structural assignments have been generally effected on the basis of the magnitude of experimental values of Mössbauer nuclear quadrupole splittings, measured at 77 K for both solid and frozen aqueous absorbers, and comparison with data calculated by the point-charge model approach.

    Notes: Stannacyclohexyl and stannacycloheptyl derivatives of dipeptides (CH2)nSnAA · xH2O (H2AA = H2GlyGly, with n = 5, x = 2 or n = 6, x = 1; H2AA = H2GlyAla, H2GlyVal, H2GlyMet, with n = 5, 6, x = 1) and stannepinyl glycylglycinate monohydrate have been obtained by the reaction of (CH2)nSnCl2 or stannepinyl dichloride with Na2AA. According to infrared and 119Sn Mössbauer data of the solid compounds, AA acts as a tridentate ONN ligand and tin has a trigonalbipyramidal environment. An analogous structure has been inferred from 1H, 13C, and 119Sn NMR data for the undissociated molecules in methanol solution.
