Abstract:

The distortion of an one dimensional transition-metal compound [Pd(cn)_2Pd(en)_2X_2]_n4+(X=Cl, Br, I) was studied by ab initio and EHT method. It was found that the degree of distortion was decided by the energy reduce of occupied orbit, interaction between metal nuclear and interaction among electrons. Base on it, the change rules of distortion and mixed-valence of [Pd(en)_2Pd(en)_2X_2]_n(4+)(M=Pt, Pd, Ni; X=Cl, Br, I) were explained reasonably. And it was shown that the δe of Pd in the complex varies linear with the deflection of d.
