摘要：
The synthesis and crystal structures of two new phosphine ruthenium polypyridine complexes [Ru(tpy)(bpy)(PR3)](2+) with R = Ph (1), Cy (2) are reported. Their geometrical parameters are intimately related to the electronic and steric properties of the phosphine ligand. Electrochemical and UV-Vis analyses showed the influence of the substituents of the coordinated phosphorus atom on the Ru-III/Ru-II potential and on the frontier orbitals energy gap. The results are discussed in terms of steric effects and net donor power of the phosphine ligands. (c) 2006 Elsevier B.V. All rights reserved.
