The infrared spectra of some phenyl-substituted pentavalent antimony compounds

Synthesis, crystal structures and in vitro antitumor activities of some organoantimony arylhydroxamates

“…In the title compounds, the very strong stretching vibrations m(C@O) is displaced to lower frequency between 1615 and 1628 cm À1 , so we can assume that there are coordination interactions between the antimony atom and the carbonyl oxygen atom of the hydroxamate group (see the crystal structures of compounds 1 and 9). In addition, the frequencies of Sb-C deformations appear between 453 and 504 cm À1 which is consistent with the literature [6].…”

“…A great number of references describing synthesis and biological activities of organoantimony carboxylates with the general formula Ar n SbX (5 À n) (n = 3, 4; X = carboxylate) have already appeared in the literature [1][2][3][4][5][6][7][8]. However, the published data on the antitumor activity of these compounds are relatively limitied [9,10].…”

Syntheses, characterizations and crystal structures of new organoantimony(V) complexes with heterocyclic (S,N) ligand

“…In the far-IR spectra, the absorption around 360 cm À1 region for all complexes 1-8, which is absent in the spectra of the ligands, may be assigned to Sb-S stretching mode of the vibration [8] and these data further supports the formation of Sb-S bond in complexes 1-8. In addition, the Sb-C absorption values are found between 472 and 488 cm À1 in all the complexes, which are consistent with that reported in other organoantimony complexes [9,10].…”

Synthesis, crystal structures and in vitro antitumor activities of some arylantimony derivatives of analogues of demethylcantharimide

“…A substantial number of references describing synthesis and applications of Ar n SbX ð5ÀnÞ (n ¼ 3, 4; X ¼ halide, alkoxyl, carboxylate, sulphonate, oxime) have appeared in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The use of antimony in medicine has been reviewed by Tiekink [15].…”
