Abstract :
The structure of the title compound, [N(C2H5)4]2[Co2(C2N3)5(H2O)4](C2N3), is a new example of a metal–dicyanamide coordination polymer which exhibits a unique three-dimensional framework of covalently linked CoII chains. All bridging dicyanamide ligands in the title structure are in the μ1,5-bridging mode. The anionic CoII-dicyanamide network is templated by tetraethylammonium cations residing in a series of channels extending along the b axis where additional non-coordinating dicyanamidate anions are also located. The framework structure is further stabilized by O—H⋯N hydrogen bonding between aqua ligands and dicyanamido ligands or the dicyanamide anion. In addition, C—H⋯N interactions are present between the tetraethylammonium cations and dicyanamide amide nitrogen atoms.
