In many respects, this is the kernel of this book. For years it has not been too clear how one could consistently account for the wide variety of transition-metal chemistry in a way that does not conflict with the equally varied phenomena of spectroscopy and magnetochemistry that are so well rationalized by ligand-field theory. There is a tendency - psychologically quite natural, no doubt - for those interested in synthetic and mainstream chemistry not to look too closely at theory and physical properties, and, of course, vice versa. However, there has always been the need, surely, to build a logical synthesis of, or bridge between, these two aspects of the same subject. We hope that our presentation in this book goes some way towards providing that overview. 

The structural and magnetochemistry of RE3Ni7B2 phases confirms an earlier structure for Mr = Gd, Tb, Dy, Ho, Er, Tm, Lu (U3CO7B2 type, P63/mmc). For Mre = Sm, Eu, Yb, however, a symmetry reduction is claimed (P6/mmm) corresponding to a different site occupation, which actually represents an occupation variant of the CeCo4B type insofar as Eu + Ni statistically occupy the 2c sites .

V,/V-bis(2-hydroxy-di-3,5-/-butylphenyl)amine forms complexes of zinc which have ligand-based redox processes with four oxidation levels of the coordinated anion.864 2 1 and 1 1 complexes are formed in the presence of zinc with the 2 1 complex coordinated in an octahedral geometry and the 1 1 complex square planar with a triethylamine ligand completing the coordination sphere. The complexes, at the different redox levels, have been investigated by EPR, spectro-electrochemistry, l I NMR, and magnetochemistry, as appropriate.

The spectroscopic data and the magnetochemistry reported are, in our view, also compatible with a formulation as Mm-OR (M = Co111, Fem) and a Mnlv-OR species. Thus the generation of a coordinated iminosemiquinone is preferred over a genuine metal-centered oxidation. A closer inspection of these interesting compounds by, for example, RR spectroscopy is definitely called for.
