Crystal structure of manganese

Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic. Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. Naturally occurring manganese is composed of one stable isotope, Mn. Several radioisotopes have been isolated and described, ranging in atomic weight from 46 u ( Mn) to 72 u ( Mn). The most sta… WebThe compounds have low-spin electronic configurations. While the manganese complexes are paramagnetic with one unpaired electron (1.65–1.70 μ B) the cobalt complexes are …
