Abstract In this paper, the structural characteristics and electro-structure of H2PO2- were discussed by means of FTIR and ab initio. The dissociating route of H2PO2-, which is in the process of electroless nickel plating activated by nickel on inertia groups, has been investigated. The average crack and different crack of P-H bond were deliberately analyzed. Moreover, the influence of both solvent and active matter on H2PO2- dissociation was studied.
