Caesium nitrite

Several double salts with alkali-metal nitrites have been described.10 Double compounds with ammonia of the formulae AgN02,NH8 AgNOa,2NH3 and AgN02,3NH3 have also been prepared.11 A double salt with caesium, AgCs(N02)2, is formed by the interaction of caesium nitrite and silver nitrite. It crystallizes in lemon-yellow needles.12... 

V. 1 Olivier a trace of iodine. L. Dieulafait found traces of lithium, rubidium, and caesium salt H. Beckurts, chlorates and perchlorates up to 5 64 per cent. M. Marcker, borates and humus C. F. Schfinbein, nitrites and ammonia R. Wagner, iodine and bromine. H. Griineberg says the former is present as iodate or periodate. 

The corresponding double nitrites of caesium, rubidium,5 silver,8 and lead,34 have also been prepared as insoluble yellow precipitates. Rosenheim and Koppel attribute 12 molecules of water to the last-named, whilst Cunningham and Perkin find 4 molecules of water after the salt has been dried over phosphorus pentoxide. 

Iridium Chlor-nitrites of Barium,1 2 Ba3(IrCl6)2.3Ba3Ir.,(N02)u Caesium,8 Css(N02)2.IrCl4 Lead,3 Pb3(N02)4.2lrCl4.2Pb(OH)2 Mercury,3 Hg3(N02)4.2lrCl4 and Silver,3 Ag3(NOi)2.IrCl1. have also been described. 

The salts of sodium react with a solution of potassium nitrite and the nitrates of bismuth and caesium, yielding a yellow, crystalline precipitate of the formula 5Bi(N02)3,9CsN02,6NaN02. This reaction is applicable to the detection and estimation of sodium.2... 

Cflftsinm nitrite, CsN02.—The nitrite is prepared by the interaction of caesium sulphate and barium nitrite, and forms a yellowish, hygroscopic, crystalline massrf1 A number of double and triple salts of the nitrite with other metallic nitrites have been prepared.12... 

Nitrosyl fluoride also catalyses the addition of chlorine monofluoride (and of fluorine) across G=0 bonds in fluorocarbonyl compounds, the reaction apparently proceeding via initial formation of a-fluoro-nitrites. Apparently, no reaction occurs between carbon dioxide and chlorine monofiuoride in the presence of caesium fluoride in the temperature range -78 to 80 G [c/. CO3 + 2F °S GF COF), (100%)], but thionyl...
