Investigations on organoantimony compounds

1977

Abstract Trichlorodiorganoantimony(V) compounds, R2SbCl3, in which the antimony atom is part of a heterocyclic ring have been synthesized. They have been converted into the corresponding tetramethylammonium tetrachlorodiorganoantimonates, [R2SbCl4]− [Me4N]+, which are hexacoordinate diorganoantimony(V) species in which the antimony-carbon bonds are forced into a cis-position. 5,5,5-Trichlorodibenzostibole, 10,10,10-trichlorophenoxantimonin, 5,5,5-trichloro-5,10-dihydrodibenz[b, e]antimonin and 5,5,5-trichloro-10,11-dihydro-5H-dibenzo[b, f]stibepin have been prepared by chlorination of the corresponding heterocyclic chlorodiarylstibines. Heterocyclic trichlorodialkylantimony(V) compounds hav…

Investigations on organoantimony compounds XI. Triorganoantimony(V) compounds containing potentially tridentate ligands

1974

Triorganoantimony(V) compounds of the types RSbVL, in which R = Me or Ph, and L represents a potentially tridentate dianionic Schiff base ligand of the ONO or SNO type, have been synthesized and investigated by spectroscopic (UV, IR, PMR) methods. Molecular weight determinations in benzene reveal the monomeric nature of these compounds. The free ligands, HL, used in this study are:,′-(methylidynenitrilo)diphenol (HSab), -(o-hydroxyphenyl)benzothiazoline (H-Sat), -(o_hydroxyanilino)crotonophenone (HBah), 4-(o-hydroxyphenylimino)--pentanone (HAah) and -acetonyl--methylbenzothiazoline (HAat). Both the UV and the IR data suggest hexacoordinate molecular structures for the complexes RSbL in whic…

Investigations on organoantimony compounds

1976

Abstract Diorganoantimony(V) complexes of the type R 2 SbClTrid (R = Me, Ph) containing dianionic, potentially tridentate Schiff-base ligands with ONO donor atoms (Trid 2− ) have been prepared and characterized. IR and NMR data suggest an octahedral coordination environment for the antimony atom with meridional arrangement of the ONO ligand atoms and a linear CSbC skeleton.
