Antimony halides simple

Class I. ELEMENTS. A. Metals. Cubic copper, silver, gold, iron, platinum, iridium. - Tetragonal tin. - Rhombohedral and Hexagonal arsenic, antimony, bismuth, tellurium, (Os, Ir). - B. Metalloids. Cubic diamond. - Hexagonal graphite. - Orthorhombic sulfur, iodine. - Monoclinic sulfur, selenium. - Class II. SULFIDES. - Class HI. HALIDES. -Class IV. OXIDES, divided into SIMPLE OXIDES and COMPLEX OXIDES, such as CARBONATES, PHOSPHATES, SILICATES, BORATES and SULFATES. 

There are no arsenic or antimony analogues of the simple ammonium or phos-phonium halides. (Of the latter, PH4CI, PH4Br, and PH4I are known, the latter forming brilliant cubes which can be sublimed like an ammonium salt.) The tetrahedral configuration of substituted arsonium ions has been demonstrated in crystalline [As(CH3)4]Br and [As(C6Hs)4]I3. 

All of the chemistry described in this Section consists of either simple halide exchange reactions (for the formation of other carbonyl halides) or deoxohalogenation reactions (for the formation of perhalomethanes), with the exceptions of the weak adduct formation observed for antimony(V) chloride and dioxide chloride. 

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... 

This article is concerned mainly with the simple halides of phosphorus, arsenic, antimony, and bismuth compounds that also contain other elements or groups will be considered only to a limited extent. Nitrogen compounds show special features associated with the absence in nitrogen of d electrons for bonding, and are not easily discussed together with compounds of the heavier elements they will therefore be omitted. Bismuth has metallic properties that differentiate its compounds from those of elements in the middle of the group the break in properties between the compounds of antimony and bismuth is not, however, so marked as that between compounds of nitrogen and phosphorus. 

A large family of complexes of type 52 and 53 (Scheme 15.14) are accessible via simple metathesis reactions between anionic Group 6 and complexes and antimony or bismuth halides [156-162], Reactions of in srT -generated alkali organostibides and bismuthides with Group 6 and 7 halides have...
