Crystal structure of catena-poly[bis-(tetra-ethyl-ammonium) [tetra-aqua-tris(μ-dicyanamido-κ²N¹:N⁵)bis(dicyanamido-κN¹)di-cobaltate(II)] dicyanamide].

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 Co^II chains. All bridging dicyanamide ligands in the title structure are in the μ_1,5-bridging mode. The anionic Co^II-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 d
