The title salt, (C2H8,N)(2)[Co(H2O)(6))](SO4)(2)center dot 2H(2)O, is isotypic with (C2H8,N)(2)[Ni(H2O)(6))](SO4)(2)center dot 2H(2)O. The Co-O bond lengths in the [Co(H2O)(6)](2+) complex cation show very similar distances as in the related Tutton salt (NH4)(2)[Co(H2O)(6))](SO4)(2) [average 2.093 (17) angstrom], but are significantly longer than in the isotypic Ni II compound (Delta d similar or equal to 0.04 angstrom). The cobalt cation reaches an overall bond-valence sum of 1.97 valence units. The S-O distances are nearly equal, ranging from 1.454 (4) to 1.470 (3) angstrom [mean 1.465 (12) angstrom]; however, the O-S-O angles vary clearly from 108.1 (2) to 110.2 (2)degrees [average bond angle 109.5 (9) ]. The non-coordinating water molecules and dimethylammonium cations connect the sulfate tetrahedra and the [Co(H2O)(6)](2+) octahedron via O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds of weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel to (001).
