چکیده
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 tetra-ethyl-ammonium 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 inter-actions are present between the tetra-ethyl-ammonium cations and dicyanamide amide nitro-gen atoms.
