Antimony trihalides complexes

Photoelectron spectra for the antimony trihalides and Sb, Cl, and Br n.q.r. spectra for a number of adducts of the trichloride and bromide have been reported. The complex SbCl3,GaCl3 has been isolated, whereas a simple eutectic only is observed in the SbCl3-AlCl3 system. Antimony and bismuth halide complexes with substituted l,2-dithiol-3-thiones can be obtained, and the...

I.r. and Raman studies have shown the formation of complexes between tributyl phosphate and both arsenic and antimony tribromides. Cryoscopy in fused arsenic tribromide is reported for a num r of inorganic and organic solutes, showing dTj X values lower than the ideal value, and with dioxan the compound 2AsBr3,3dioxan, melting at 64 °C, is formed. Arsenic and antimony trihalides give a-bonded transition-metal derivatives, such as X2E[Fe(CO)2(Cp)]J, where E = As or Sb and X = Cl or Br, on reaction with metal carbonyl anions or metal carbonyls with metal-metal bonds. ... 

The trihalides of arsenic and antimony are known to act as acceptor molecules and to form adducts with various donor molecules. The complexes formed with 2,2 -bipyridyl are appreciably ionized in nitrobenzene 9,1 and simple ionization has been proposed 91> 92h... 

Diorgano tellurium dihalides form complexes with iodine and interhalogen compounds organic compounds with N, P, O, S, and Se donor atoms boron, aluminum, and gallium trihalides antimony pentachloride and mercury(II) halides. 

Other oxyhalides, mostly oxychlorides and oxybromides, result from the controlled hydrolysis of the trihalides, and are of interest for two main reasons. First, they are quite unrelated to the oxyhalides of bismuth. Although both antimony and bismuth form compounds MOX the structures of the antimony compounds are quite different from those of the compounds BiOX, which have been described on p. 408. The more complex oxyhalides of Sb have no analogues among Bi compounds. Second, a feature of the published structures of the antimony oxyhalides is the coordination of Sb by either three or four O atoms. It should perhaps be remarked here that the investigation of the structures of these complex compounds is difficult, and the precise positions of the O atoms are by no means certain. However, it appears that a feature of these compounds is the formation of extended Sb—O systems, generally layers, interleaved with halogen... 

The preparation of 1 1 complexes of arsenic, antimony, and bismuth trihalides with dithio-oxamides has been reported.647 I.r. spectra of the arsenic compounds point strongly to the probability of dimeric, octahedral structures, but with the two heavier Group V elements square-pyramidal structures have been suggested. Crystalline adducts 2MBr3,3dioxan, where... 

Bismuth trihalides along with the analogous arsenic and antimony compound form complexes with metal carbonyls with bismuth, however, only neutral species such as Cl2BiFe(CO)2Cp and Bi[Co(CO)3PPh3l3 were isolated.
