Abstract:
The electron structure of the NixTiSe2 system has been studied by the electromotive force (EMF) method in Cu|Cu+|NixTiSe2 and Na|Na+|NixTiSe2 electrochemical cells. Two critical transitions have been found in this system at x = 0.25 and x = 0.35. At these compositions, a change in the nature of the chemical bond of nickel with its local environment occurs. The simple and useful EMF method has been applied as the instrument to study features of electron structure. A comparative analysis of critical points in the electronic structure of the MexTiSe2 (Me = Fe, Co, Ni) intercalate compounds was carried out.

02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
