Manganese chain structure

Fig. 19 The low-pH chain structure of manganese /)-(phosphono-methyl)benzoate, with ail carboxylate oxygens and half the phosphonate oxygens protonated.59 Gray spheres denote carbon, red oxygen, white hydrogen, and green phosphorus, with MnOs octahedra in blue.

The shift of the amide I mode (FTIR spectra) from 1657 to 1646 cm-1 was attributed to a change in the a-helix native structure to fl-sheets, secondary structure conformations. Atomic Force Microscopy (AFM) images display the coating of the manganese oxide surface as well as the unfolding in a ellipsoidal chain of the protein molecules after adsorption and immobilization on the surface. 

First attempts to obtain 3d-4f-based regular chains were made with Cu-Tb chains that show characteristic features of SCM but without structural characterization [84, 85]. Similarly, Co - Dy based chains were obtained but showed very weak x" lx ratio making the analysis of the magnetic slow relaxation difficult [86]. Lastly, some magnetic interplay between manganese oxide chains and Dy09 units...
