Synthesis and structure of the [MnIV(biguanide)3]4+ ion: the simplest source for water-stable manganese(iv)
Abstract
Aqueous oxidation of alkaline biguanide sulfate with KMnO4 followed by crystallisation from 2 M HNO3 yields the mononuclear [Mn(bigH)3]4+ ion, which has been characterised crystallographically and provides an easy route to mononuclear, water-stable manganese(IV).
