Abstract: The crystal structure of the title compound, [Co(NO₃)(bipy)₂]₂[MoO₄]·7H₂O (bipy is 2,2'-bipyridine, C₁₀H₈N₂), contains the isomers and of the cation [Co(NO₃)(bipy)₂]⁺, self-assembled through complementary -, C-H and C-HO interactions, leading to an intricate two-dimensional array. The final three-dimensional network is sustained via extensive hydrogen bonding among the cations, uncoordinated water molecules and molybdate anions, which are accommodated in between adjacent cationic two-dimensional arrays. In the cations, the metal centres adopt a distorted octahedral geometry due to the coordination of the N atoms of two bipy molecules and one bidentate nitrate ligand.
