“…This indicates that SbSI converts to Sb 2 S 3 by a decomposition reaction, and then gradually precedes another decomposition process. On the basis of our TG data and the literature, the decomposition reaction is likely 3SbSI-Sb 2 S 3 (residue)þSbI 3 (vapor) [13]. We also performed the XRD experiment for SbSI upon annealing at 400 1C in a This confirms that SbSI converts to Sb 2 S 3 upon annealing to 400 1C in N 2 condition.…”

“…Although SbSI shows many interesting properties, the detailed studies on one-dimensional (1-D) structure of SbSI are relatively few. SbSI has been prepared by evaporation, vapor (chemical) transport, thermal decomposition process of a precursor, laser deposition, and laser direct-write methods [10][11][12][13][14]. More conveniently, sonication and hydrothermal methods have been introduced [3,[15][16][17][18].…”

“…The reports on structural characterization of antimony(III) triiodide complexes with thione/thiol ligands are rare in the literature. Sulfur containing ligands, such as thiones/thiols, − thioethers, , and dithiocarbamates, − have been used to prepare stable Sb(III) iodide complexes. These include S(C 6 H 4 S) 2 SbI, [{Sb( k 3 -Tm Me )(μ 2 -I)I} 2 ] and [Sb( k 3 -Tm Me )I(μ 2 -I)] 2 (Tm Me = hydrotris(methimazolyl) borate), LSb(μ-I)2(μ-S)SbL (HL = tetraphenyldithioimidodiphosphine (SPPh 2 NHPPh 2 S)), SbI(SC 6 H 2 Me 3 -2,4,6), and S(CH 2 CH 2 S) 2 SbI and (CH 2 S) 2 SbI .…”

Eight new antimony(III) iodide complexes of the heterocyclic thioamides, 2-mercapto-1-methylimidazole (MMI), 2-mercaptobenzimidazole (MBZIM), 5-ethoxy-2-mercaptobenzimidazole (EtMBZIM), 2-mercaptothiazolidine (MTZD), 3-methyl-2-mercaptobenzothiazole (NMeMBZT), 2-mercapto-3,4,5,6-tetrahydropyrimidine (tHPMT), 2-mercaptopyridine (PYT), and 2-mercaptopyrimidine (PMT) of formulas {[SbI(3)(MMI)(2)].MeOH} (1), [SbI(3)(MBZIM)(2)] (2), {[SbI(2)(mu(2)-I)(EtMBZIM)(2)](2).H(2)O} (3), [SbI(3)(MTZD)] (4), [(NMeMBZT)SbI(2)(mu(2)-I)(2)(mu(2)-S-NMeMBZT)SbI(2) (NMeMBZT)] (5), {[SbI(3)(tHPMT)(3)].MeOH} (6), [SbI(3)(PYT)] (7), and [SbI(3)(PMT)(2)] (8), have been synthesized and characterized by elemental analysis, FT-IR spectroscopy, FT-Raman spectroscopy, and TG-DTA analysis. The crystal structures of 3, 4, 5, 6, and 7 were also determined by X-ray diffraction. The complexes show interesting structural motifs. Complex 6 is a monomer, with octahedral (Oh) geometry around the metal ion formed by three sulfur and three iodide atoms. Complexes 3 and 5 are dimers, with a square pyramidal (SP) geometry in each monomeric unit, while complexes 4 and 7 are polymers with pseudotrigonal bipyramidal (psi-TBP). Two or three sulfur atoms from thioamide ligands and three iodide atoms are bound to Sb atoms forming building blocks for the dimers and polymers. Strong intramolecular interactions between mu(2)-I and/or mu(2)-S and Sb atoms stabilize both structures. In dimer complex 5, two terminal iodide and one terminal sulfur atom are bonded to the Sb ion, while two mu(2)-I and one mu(2)-S bridging atoms bridge the metal ions forming psi-Oh geometry. Computational studies using multivariant linear regression (MLR) and artificial neural networks (ANN) and considering biological results (50% inhibitory concentration, IC(50)) as dependent variables derived a theoretical equation for IC(50) values of the complexes studied. The calculated IC(50) values are compared satisfactorily with the experimental inhibitory activity of the complexes measured. Complexes 3-7 were used to study their influence upon the catalytic peroxidation of linoleic acid by the enzyme Lipoxygenase (LOX). Compounds 1-8 were also tested for in vitro cytotoxicity, and they showed mostly a moderate cytostatic activity against a variety of tumor cell lines but comparable with those found for the antimony(III) chloride and bromide complexes, reported earlier [Ozturk et al. Inorg. Chem. 2007, 46, 2861-2866; Ozturk et al. Inorg. Chem. 2009, 48, 2233-2245].

The antimony aminoalkoxide and aminothiolates Sb(ECH 2 CH 2 NMe 2 ) 3 [E = O (1), S (2)] were synthesized and their ability to form adducts with other metal moieties investigated. Compound 1 forms 1:1 adducts with NiI 2 (3) and M(acac) 2 [M = Cd (4), Ni (5)], while 2 undergoes ligand exchange with AlMe 3 to afford Me 2-AlSCH 2 CH 2 NMe 2 (6). The structures of 2-4 and 6 were determined. Compound 2 incorporates three S,N-chelating ligands though the inter-1699 action with nitrogen is weaker than in analogous alkoxide complexes. Product 3 reveals one iodine has migrated from nickel to antimony, and all three alkoxide ligands bridge the two metals through μ 2 -O atoms. In contrast, in 4, only one alkoxide links the antimony and cadmium. Compound 6 adopts the same structure, a chelating S,N ligand generating a tetrahedral center at aluminum, as known tBu 2-AlSCH 2 CH 2 NR 2 species (R = Me, Et).
