| Popis: |
The crystal structure of the title compound, [Co(NO3)(bipy)2]2[MoO4]·7H2O (bipy is 2,2′-bipyridine, C10H8N2), contains the isomers Δ and Λ of the cation [Co(NO3)(bipy)2]+, self-assembled through complementary π–π, C—H⋯π and C—H⋯O 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. |
