Group 7 manganese

A 8-hond is formed by the face-on overlap of two d z (or two dyz, or two d y) orbitals. The resultant MO possesses two nodal planes that contain the internuclear axis  [Pg.611]

Metallic Mn is slowly attacked by water and dissolves readily in acids (e.g. equation 21.35). The finely divided metal is pyrophoric in air, but the bulk metal is not attacked unless heated (equation 21.36). At elevated temperatures, it combines with most non-metals, e.g. N2 (equation 21.37), halogens (equation 21.38), C, Si and B (see Sections 12.10, [Pg.611]

Manganese exhibits the widest range of oxidation states of any of the first row J-block metals the lowest states are stabilized by 7r-acceptor ligands, usually in organometallic complexes (see Chapter 23). However, dissolution of Mn powder in air-free aqueous NaCN gives the Mn(I) complex Na5 Mn(CN)6]. [Pg.611]

Similarly, the cobalt acetate-catalyzed autoxidation of p-cymene afforded mainly p-isopropylbenzoic acid,243,244 246 derived from selective oxidation of the methyl group. Manganese acetate, on the other hand, was involved in a catalyzed autoxidation,... [Pg.312]
