 * I vaguely remember seeing similar things in the past: however, Cotton & Wilkinson is quite formal that there is disproportionation when MnO2 dissolves in concentrated alkali. There are also lithium and sodium manganites, MMnO2 (that is manganese(III), ), but these are probably best considered as mixed oxides. Physchim62 (talk) 16:14, 26 June 2010 (UTC)
