" stibacetin," which was the first aromatic compound of antimony to be used in the treatment of leishmaniasis, many aromatic compounds of antimony have been introduced. Von Heyden also introduced sodium meta-chloro-para-acetylamino stibinate, known as No. 471 or " stibosan," and an amine salt of p-amino-phenyl-stibinic acid known as No. 693 iboth of which proved to be very effective in the trea...

A series of antimony-doped Ba(8)Ga(16)Ge(30) clathrates was grown as large crystals from gallium flux. These compounds form in the cubic space group Pm(-)3n, with the unit cell parameter varying from 10.784(5) to 10.9008(6) A as the amount of GaSb substituting for germanium atoms in the framework is increased. It was found that more antimony than extra gallium was incorporated into the material...

Two mucocutaneous leishmaniasis cases resistant to therapy are reported here. After the failure of initial therapies (antimony, amphotericin B and/or pentamidine) patients received a low-dose schedule: one ampoule of meglumine antimoniate (405 mg of pentavalent antimony [Sb v]) by intramuscular injection, three times a week until complete healing of the lesions. One patient was cured with a tot...

The generation of antimony clusters in the size range from Sb to SbSoo is reported. The clusters are created by inert gas condensation and detected by a time-ofiflight mass spectrometer. Condensation of clusters of knvwn sizes onto a cold substrate is suggested as a technique which enables investigations of amorphous substances as a function of order. To reveal the topology of amorphoussolids a...

In Cs(2)SbCl(6) and related compounds antimony appears as Sb(III) and Sb(V) in alternate halide octahedra. The optical spectrum contains "mixed valence" peaks assigned to Sb(III) --> Sb(V) transfer near 18 and 27 kK (cm(-1)). In addition there is a peak near 31 kK assigned to an internal transition on Sb(III) and one near 37 kK assigned to Sb(V), mixed with the absorption edge of the crystal. T...

Antimony (Sb) is a naturally occurring toxic element commonly associated with arsenic (As) in the environment and both elements have similar chemistry and toxicity. Increasing numbers of studies have focused on microbial As transformations, while microbial Sb interactions are still not well understood. To gain insight into microbial roles in the geochemical cycling of Sb and As, soils from Sb m...
