The trans(O)-cis(C)-bis(pyridine-2-carboxylato)dicyanocobaltate(III) ions, [CO(Pic)(2)(CN)(2)](-), crystallize from acid medium with three water molecules per two crystallographically nonequivalent complexes whose charge is compensated by protons. One of the water molecules forms an oxonium ion (H3O+) with a proton. The other two water molecules bound to each other through a short hydrogen bond O-H center dot center dot center dot O (2.403(2) angstrom) and thus forming (H5O2)(+) cations is another proton site. The (H3O)(H5O2)[Co(Pic)(2)(CN)(2)](2) crystals are monoclinic: a = 10.7027(7) angstrom, b = 25.786(1) angstrom, c = 11.4865(8) angstrom, beta = 91.411(9)degrees, Z= 4, space group P2(1)/n.
