The monodentate 4,4'-bipyridine complex tetraaquabis(4,4'-bipyridine)zinc(II) bis(4-carboxybenzenesulfonate)

L.-P. Zhang and L.-G. Zhu

Abstract: The molecule of the title salt, [Zn(C₁₀H₈N₂)₂(H₂O)₄](C₇H₅O₅S)₂, resides on a centre of symmetry and the coordination geometry of the Zn atom is octahedral. Each 4,4'-bipyridine ligand coordinates to the Zn atom in a monodentate fashion and the second N-atom donor of the 4,4'-bipyridine ligand forms a hydrogen bond with a sulfonate O atom. Hydrogen-bonding interactions between cations and anions generate a three-dimensional architecture and enhance the stability of the structure.
