摘要：

Ni(II) ions in the presence of excess of pyrophosphate catalyze the decomposition of HSO5-, while forming relatively stable Ni-III(P2O7)(n)(3-4n) complexes. Excess pyrophosphate stabilizes the trivalent nickel species, Ni-III(p(2)O(7))(n)(2-4n)(aq), i.e. increases considerably its lifetime. (C) 2013 Elsevier B.V. All rights reserved.
