摘要
The electrophilic substitution reactions Ni(II)-->M(II) (M = Co, Cu, Zn, Cd) occurring in nickel(II) hexacyanoferrate(II) gelatin-immobilized matrix materials on their contact with aqueous solutions of corresponding chlorides MCl were studied. During contact, Ni(II) is partly substituted by the other metal to form heteronuclear hexacyanofeffates(II) of nickel(II) and corresponding double-charged ions, and none of the studied reactions involves complete substitution of Ni(II) until the mononuclear hexacyanoferrate(II) M-2[Fe(CN)(6)] has formed.
