Ammonium hexanitrocerate

A 500-ml, three-necked, round-bottomed flask fitted with a sealed mechanical stirrer and an outlet leading to a gas bubbler, is charged with a solution containing 4.0 g (0.0208 mole) of cyclobutadieneiron tricarbonyl2 [tricarbonyl( 4-l,3-eyclobutadiene)iron] and 2.0 g. (0.0185 mole) of freshly sublimed p-benzoquinone (2,4-cyclohexadiene-l,4-dione) (Note 1) in 72 ml. of acetone and 8 ml. of water. To the vigorously stirred, ice-cold solution, approximately 40-42 g of ceric ammonium nitrate [ammonium hexanitrocerate(IV)] (Note 2) is added portion-wise over a period of 10-12 minutes (Note 3), until the carbon monoxide evolution has ceased. The reaction mixture is then poured into 600 ml.

Reaction of ammonium hexanitrocerate and cyclopentadienylsodium under inert conditions gives tris(cyclopentadienyl)cerium and sodium nitrate, removed by filtration before evaporation of solvent [1]. When the filtration step was omitted, and the evaporated solid mixture was heated to 75°C, a violent explosion occurred. This may have involved complexes of the type Ce(N03)Cp2.NaN03[2], but a direct redox reaction between the reactive CeCp3and the oxidant is also possible.

When MeOH solution is mixed with a solution of ammonium hexanitrocerate(IV), the spectrum of the coloured solution shifts due to the replacement of a nitro group by OMe. The absorbance at the wavelength of maximum absorption (against a reagent blank) is linearly related to [MeOH]. 

Add 30 cm concentrated sulphuric acid slowly to 399 cm cooled water and dissolve in the solution 10 g propanedioic acid, 3.9 g potassium bromate and 0.4 g ammonium hexanitrocerate(IV). Add to the solution drops of 0.025 M ferroin indicator (>14 cm ) to give a visible colour. Stir magnetically and note the change in colour from blue to red. Alternatively, insert a platinum electrode into the solution and dip a calomel electrode through a salt bridge in the solution. Connect the two electrodes to a mV meter and...
