metal-organic compounds
In the title compound, (C6H19N4)[Co(CO)4], the cations are linked via N—HN hydrogen bonds in a two-dimensional (2D) grid that takes the form of a buckled sheet. Channels between sheets are occupied by the [Co(CO)4]− anions, which are linked to the cation network via N—HO and N—HπCO hydrogen bonds. Both types of cation–anion hydrogen bond are uncommon. Indeed, this is the first report of a structurally characterized N—HπCO hydrogen bond.
