We have researched M2Cl4(PH3)4(M=Cr、Mo、W) molecule by DFT. The optimization and energy decomposition are carried under D2d symmetry restriction . We find that the metal-metal bond distance of Cr -Cr is 1.737A,Mo-Mo is 2.157A and W-W is 2.286A.The energy decomposition shows that E(Cr-Cr)<< E (Mo-Mo)< E(W-W) , the stability of these compounds is related to the ligand steric effect and the overlap of the d orbit of metal atomic.
