Spectromagnetic properties

The basic properties of nickel and the coordination chemistry of nickel reported until 1983 have been comprehensively described in Comprehensive Coordination Chemistry (CCC, 1987). Hence, work published prior to 1983 will not be mentioned here, and the reader should generally refer to the respective chapters of CCC—only at some points specific reference to CCC is given. Also, the basic geometric preferences and the electronic and spectromagnetic properties of nickel in its various oxidation states will not be recapitulated, since an excellent overview is included in the first edition and only selected recent advances are added in this second edition. 

The electronic spectra and spectromagnetic properties of nickel complexes have been exhaustively described in CCC (1987)—in particular for Ni11. Hence, the present discussion will be restricted to selected examples of more recent work and emerging new methods. 

Electronic Spectra and Spectromagnetic Properties of Nickel(II) Complexes 45... 

The Schiff bases have contributed to a large extent to the development of the coordination chemistry of nickel(II), particularly those obtained by the condensation of salicylaldehyde with various mono- and poly-dentate amines. A large number of nickel(II) complexes have been synthesized with these ligands exhibiting all of the possible coordination geometries, spin states and spectromagnetic properties. The early complexes of nickel(II) with different salicylal-dimines have been covered extensively in a number of review articles.2246-2252... 

Spectromagnetic properties of some tetrahedral complexes have been investigated in detail.2330-2332...

In this section spectral and magnetic data on selected nickel(II) complexes are presented. The purpose of this section is that of showing some of the most relevant spectromagnetic studies on nickel(II) complexes. Particular emphasis will be given to work where a correlation between the properties and the electronic structure of nickel(II) complexes has been investigated. Much information is to be found in the tables, albeit without any detailed comment.
