hydrazonium Chem.|haɪdrəˈzəʊnɪəm|
[f. hydrazine + -onium.]
a. = hydrazinium a.
b. = hydrazinium b.
See the note s.v. hydrazinium.
[1876Jrnl. Chem. Soc. ii. 528 The author [sc. E. Fischer] has isolated a body of the formula C6H5.N2H2(C2H5)(C2H5 Br), which he names phenyldiethylhydrazoniumbromide. ]1949Chem. & Industry 26 Feb. 134/2 [c blue]The ions derived from hydrazine are also troublesome. The one most commonly encountered, N2H5+, is called hydrazinium in the 1940 Rules but hydrazonium in Chemical Abstracts (1945). Since the ion is essentially a substituted ammonium, the latter is strictly the more correct, but neither affords a means of distinguishing N2H5+ from N2H6++, which occurs in a few compounds. The two names could be used in fact for this purpose, but the distinction is best achieved, without confusion, by writing[/c]
N2H5+Hydrazonium (I) or (+ 1)
N2H6++Hydrazonium (II) or (+ 2)
. 1953 C. C. Clark Hydrazine iii. 36 The asymmetric dialkyl hydrazines are also strong bases. They react quantitatively with active alkyl chlorides to form water soluble hydrazonium salts: R2NNH2 + R′X → R2NNH2.R′X.1954Chem. & Engin. News 6 Sept. 3548/3 As a name for the ion H2N.NH3+ there has been some division of usage between ‘hydrazonium’ and ‘hydrazinium’; and some have applied one or other of these names to the ion +H3N.NH3+ as well as to the ion of single charge. The newly revised inorganic rules propose to settle the question by naming N2H5+ ‘hydrazinium (1+)’ and N2H62+ ‘hydrazinium (2+)’. This does not seem to us an ideal solution, to give two different ions (which are not isomers) the same name except for an affixed numeral. Might not the name ‘hydrazinium’ be retained for N2H5+ and some such name as ‘hydrazidiinium’ coined for N2H62+? 1955[see hydrazinium]. 1957[see sense c].
c. [Cf. ] The ion R{b2}N·NH3+ that results from the addition of a proton to a hydrazone; also, any substituted ion derived from this in which univalent radicals replace one or more of the hydrogen atoms.
1957Chem. Rev. LVII. 1022 The cation having the formula R3N+NR2 has been given many names. Emil Fischer called the first known representative of this type a ‘hydrazonium bromide’ but later referred to the same compound as an ‘azonium bromide’. Chemical Abstracts has used the names ‘azinium’, ‘azonium’, ‘hydrazinium’, and, most commonly of late, ‘hydrazonium’ for the same type. As a logical extension of the recommendations recently made for naming [H3NNH2]+, it is suggested that the name ‘hydrazinium’ be adopted... It is suggested here that the name ‘hydrazonium’ be restricted to salts of hydrazones (including quaternary salts). 1966P. A. S. Smith Chem. Open-Chain Org. Nitrogen Compounds II. ix. 149 Quaternary hydrazinium salts can also be obtained by the hydrolysis of quaternary hydrazonium salts (R3N+{b1}N = CR2X-) . |
