rhenate Chem.|ˈriːneɪt|
[f. rhenium + -ate4.]
A salt of the anion ReO42-. So ˈrhenic acid, H2ReO4, the parent acid of these salts, which is unstable and is known only in solution.
1929Chem. Abstr. XXIII. 1833 A soln. of black ReO2 in dil. HNO3 gives a yellow-red coloration, yellow with NaOH, from which Ca(OH)2 or Ba(OH)2 ppts. bright yellow salts, rhenates, stable only in alk. soln. 1932J. W. Mellor Comprehensive Treat. Inorg. Chem. XII. lxv. 478 The yellow product in all these cases is either an acidic soln. of rhenic acid, H2ReO4, or a salt of that acid, namely the rhenates, R12ReO4. 1950N. V. Sidgwick Chem. Elements II. 1292 Rhenium trioxide is formally the anhydride of rhenic acid H2ReO4, the salts of which can be obtained in solution. 1962J. E. Fergusson et al. in B. W. Gonser Rhenium 38 Of the complex compounds of Revi, the green rhenate BaReO4 has been prepared as mixed crystals with BaSO4. 1973R. D. Peacock in J. C. Bailar et al. Comprehensive Inorg. Chem. xxxix. 940 Concentrated alkali induces dismutation to perrhenate and dioxide, so that it is not possible to prepare rhenates(VI) in aqueous solution—alkali fusion in the absence of air is necessary. |
