Nitrosyl stibines

There are now a substantial number of nitrido complexes of osmium(VI) and osmium(IV) as well as the osmiamate ion [OsVII 03N]. In addition to the ammine and ethylenediamine complexes, much recent work has been carried out on the bipy, phen and terpy complexes, often in connection with research into the photodissociation of water. The nitrosyl chemistry of the element, though seemingly not as extensive as that of ruthenium, has received much attention, and there has been considerable work on the phosphine, arsine and stibine complexes. 

General chemistry. The commonest oxidation states in the phosphines, arsines and stibines of osmium are II and III, but there are a number of osmium(IV) species and, with oxo, nitrido and hydrido ligands, osmium(VI) with carbonyls there are examples of osmium(0) and with nitrosyls (pp. 549-551) also of the 0 and — II states. Although the stereochemistry is octahedral in most cases... 

ANTIMONY or ANTIMONY BLACK (7440-36-0) Dust or powder forms explosive mixture with air. Reacts violently with strong oxidizers and acids, especially halogenated acids, producing toxic stibine gas (antimony hydride). Reacts violently with anunonium nitrate, bromine, bromine azide, bromine tri fluoride, bromoazide, chloric acid, chlorine, chlorine monoxide, chlorine trifluoride, dichlorine oxide, disulfur dibromide, fluorine, halogens, iodine, iodine pentafluoride, nitrosyl fluoride, nitryl fluoride, potassium dioxide, potassium nitrate, potassium permanganate, potassium peroxide, sodium nitrate, sodium peroxide. Forms explosive V-chlorodimethylamines with chloric and perchloric acid. 

Ruthenium(II), d, is known as the binary bromide and as [RuCU] ". The richer complex chemistry involves stable compounds with cyanide, amines, halides, water, nitrosyl, carbonyl, hydride, phosphine, arsine, stibine, arene, and cyclopentadienyl ligands. [RuCl2(PPh3)2] is used as a catalyst. Ruthenium(II) is a good itt-donor and...
