摘要：

The electrochemistry behaviour of compounds [Pd(dmba)(mu-X)](2) [X = Cl(1), NCO (2), NCS (3), CN (4)] and [Pd(dmba)(MeCN)(2)][NO3] (5) (dmba = N,N-dimethylbenzylamine, MeCN = acetonitrile) are reported, The experimental results showed the reduction of Pd (II) to Pd (I) for complexes 1-3 while 1 was the only one to show the reduction of Pd (1) to Pd (0), It was observed that the electrochemical stability of these compounds decreased in the order: [Pd(dmba)(mu-CN)](2) (4) > [Pd(dmba)(mu-NCO)](2) (2) > [Pd(dmba)(mu-SCN)](2) (3) > [Pd(dmba)(MeCN)(2)][NO3] (5) > [Pd(dmba)(mu-Cl)](2) (1).
