Abstract:

Theoretical studies on a series of complexes M(bpy)32+ (M=Fe, Ru, Os) are carried out with DFT method at B3LYP/LanL2DZ level .The electronic structure and related chemical properties of complexes M(bpy)32+,in particular, the regularities of the centre atomic effects on coordination bond lengths, spectroscopical properties, atomic net charge populations and the chemical stabilities of M(bpy)32+,have been investigated. The results obtained may be useful as references for the synthesis of the complexes, the mechanism analysis on photochemistry, electrochemistry and catalysis chemistry of the complexes, etc.
