Manganese nuclear properties

In order to explain the spectroscopic properties, particularly nuclear magnetic resonance, of the complexes (CO)5Mn CH2 CH2 CHR Mn(CO)5 (R = H or Me), King (55) postulated an interaction between the hydrogen atoms of the alkyl chain and the manganese atoms. In the... 

This volume of the Handbook illustrates the rich variety of topics covered by rare earth science. Three chapters are devoted to the description of solid state compounds skutteru-dites (Chapter 211), rare earth-antimony systems (Chapter 212), and rare earth-manganese perovskites (Chapter 214). Two other reviews deal with solid state properties one contribution includes information on existing thermodynamic data of lanthanide trihalides (Chapter 213) while the other one describes optical properties of rare earth compounds under pressure (Chapter 217). Finally, two chapters focus on solution chemistry. The state of the art in unraveling solution structure of lanthanide-containing coordination compounds by paramagnetic nuclear magnetic resonance is outlined in Chapter 215. The potential of time-resolved, laser-induced emission spectroscopy for the analysis of lanthanide and actinide solutions is presented and critically discussed in Chapter 216. 

Many fewer high-nuclearity cages are known for cobalt than for manganese or iron, and their magnetic properties have not been well studied. Unless otherwise stated, magnetic data have not been reported for the following complexes. 

The copper/zinc- and manganese-containing superoxide dismutases are the only metalloproteins that are able to enhance the nuclear magnetic relaxation rate of F to an extent that makes this property detectable at the protein concentration usually present in most cells (Rigo et al., 1979). 

Rare-earth intermetallic compounds with iron are analysed more easily by NMR than those with cobalt or manganese, because the Fe moment is less sensitive to the environment. Thus many NMR studies were reported despite the disadvantageous NMR properties of the favourite Mossbauer nucleus Fe (small natural abundance, small nuclear magnetic moment). was the favourite non-magnetic rare-earth NMR probe.
