New antimony(III) bromide complexes with the heterocyclic thioamides, thiourea (TU), 2-mercapto-1-methylimidazole (MMI), 2-mercapto-benzimidazole (MBZIM), 2-mercapto-5-methyl-benzimidazole (MMBZIM), 5-ethoxy-2-mercapto-benzimidazole (EtMBZIM), 2-mercapto-3,4,5,6-tetrahydro-pyrimidine (tHPMT), 2-mercaptopyridine (PYT), 2-mercapto-thiazolidine (MTZD), 3-methyl-2-mercaptobenzothiazole (MMBZT), and 2-mercaptopyrimidine (PMTH) of formulas [SbBr(3)(TU)(2)] (1), [SbBr(3)(MMI)(2)] (2), {[SbBr(2)(MBZIM)(4)](+) [Br](-) H(2)O} (3), {[SbBr(2)(mu(2)-Br)(MMBZIM)(2)](2)} (4), {[SbBr(2)(mu(2)-Br)(EtMBZIM)(2)](2) MeOH} (5), {[SbBr(3)(mu(2)-S-tHPMT)(tHPMT)](n)} (6), {[SbBr(2)(mu(2)-Br)(PYT)(2))(n)} (7), {[SbBr(2)(mu(2)-Br)(MTZD)(2)](n)} (8), [SbBr(3)(MMBZT)(2)] (9), and {[SbBr(5)](2-)[(PMTH(2)(+))(2)]} (10) have been synthesized and characterized by elemental analysis, conductivity measurements, FTIR spectroscopy, FT-Raman spectroscopy, TG-DTA analysis, and X-ray powder diffraction. The crystal structures of 3, 4, 5, 6, 7, 8, and 10 were also determined by X-ray diffraction. In 3, four sulfur atoms from thione ligands and two bromide ions form an octahedral (O(h)) cationic [SbS(4)Br(2)](+) species in which the two bromide anions lie at axial positions. A third bromide counteranion neutralizes the whole complex. 4 and 5 are dimers, whereas 6, 7 and 8 are polymers, built up by monomeric units of square pyramidal (SP) geometry around the metal center, which were formed by two sulfur atoms of thioamide ligands and three bromide ions. Finally, 10 is ionic salt containing 1D polymeric network of {[SbBr(5)](2-)}(n) anions and (-)[(PMTH(2)(+))2] counter cations in the lattice. The complexes showed mostly a moderate cytostatic activity against a variety of tumor cell lines.
