It is considered that hydrous manganese dioxides and their derivatives used as sorbents belong to the crystallographic group of a-Mn02, where the atomic ratio 0 Mn<2, and the presence of side ions is a prerequisite of the very existence of this type of the crystalline lattice. For example, in various synthetic samples, the 0 Mn ratio can vary from 1.95 to 1.70. This means that the oxidation state of manganese in synthetic manganese oxides is seldom equal to 4. [Pg.483]

The oxalate [Mn(C204)3], like the catecholate [Mn(cat)3] compounds, can be readily oxidized to Mn state. Otherwise, oxalate can form polymers and the combination of phosphate and oxalate in fomting hybrid framework materials has been also explored. Several hydroxycarboxylates exist as monomers or polymers and the first mononuclear manganese citrate complex, (NH4)4[Mn(C6H507)2], has been recently isolated and crystallographically characterized. ...
