Antimony, dithiocarbamate complexes

Antimony-121 Mossbauer Data for Antimony Dithiocarbamate Complexes... [Pg.40]

Antimony Sb(III) and Sb(VI) adsorbed as ammonium pyrrolidine dithiocarbamate complexes onto Cis bonded silica Graphite furnace AAS 0.05 [xg/1 [860]... [Pg.291]

Extraction of the Sb(III) dithiocarbamate complexes from acid media allows antimony to be separated from many metals [9-11]. A preliminary extraction of Bi and Cu dithiocarbamates can be carried out after oxidation of Sb(III) to Sb(V). [Pg.92]

Thus the results from the studies of copper bis-dithiocarbamate complex reactions with tin(22) antimony(22) and copper(23) halides show formation of copper(II) mixed-ligand complexes. [Pg.86]

The structural chemistry of some metal dithiocarbamates, i.e. systematics, coordination modes, crystal packing, and supramolecular self-assembly patterns of nickel, zinc, cadmium, mercury,363 organotin,364 and tellurium,365 366 complexes has been thoroughly analyzed and discussed in detail. Supramolecular self-assembly frequently occurs in non-transition heavier soft metal dithiocarbamates. Thus, lead(II),367 bismuth(III)368 zinc,369 cadmium,370 and (organo)mercury371 dithiocarbamates are associated through M- S secondary bonds, to form either dimeric supermolecules or chain-like supramolecular arrays. The arsenic(III)372 and antimony(III)373 dithiocarbamates are... [Pg.614]

Phosphorus is present in zinc dialkyldithiophosphate and deactivate platinum catalysts in engine exhaust systems. Using zinc, antimony and oxothiomolybdate dialkyl-dithiocarbamate (MoDTC) complexes alone or in combination with other lubricating oil additives appears to solve this problem. Antimony complexes are used also as extreme pressure agents while molybdenum ones as friction modifier additives (Hill et al., 1994). Analyses of Zn(dtc)2 decomposition using the thermogravimetric method, flash vacuum pyrolysis, and four-ball machine... [Pg.198]

Antimony has a great affinity for charged sulfur ligands which include thiolates, xanthates (R0CS2 ), dithiocarbamates (R2NCS2 ), and dithiophosphates ((RO)2PS2 ). In contrast to arsenic, where this chemistry is limited to oxidation state III, antimony forms compounds in oxidation states III and V. The xanthate, dithiocarbamate, and dithiophosphate complexes are mostly made by reaction of antimony(III) halides or organohalides with Na, NH4, or Ag salts of the acids. Complexes... [Pg.491]
