Synthesis and Crystal Structure a Two-Dimensional Coordination Polymer: [Cd(μ-N3)(μ-HL)(H2O)]n [HL = Monodeprotonated 2,2′-bypyridine-3,3′-diol]

Original Paper


Hydrated cadmium perchlorate reacted with sodium azide and 2,2′-bypyridine-3,3′-diol (H2L) in ethanol solution and resulted in the formation of a two-dimensional coordination polymer: [Cd(μ-N3)(μ-HL)(H2O)]n. The complex has been characterized by elemental analysis and IR spectrum, and its crystal structure determined by X-ray crystallography and the complex crystallizes in the monoclinic system with space group P21/c and a = 7.2849(14), b = 9.9568(19), c = 17.058(3) Ǻ, β = 102.254(2)°. In the complex both azide anion and monodepronated 2,2′-bypyridine-3,3′-diol anion (HL) act as bridge ligands and led to the formation of a two-dimensional sheet structure on (100) plane, and the O–H⋯N hydrogen bond made the sheets pile up along [100] direction, which forms a supramolecular three-dimensional structure.

Graphical Abstract

The title two-dimensional Cd(II) coordination polymer was synthesized by cadmium perchlorate, sodium azide and 2,2′-bypyridine-3,3′-diol and its crystal structure determined. Single crystal X-ray diffraction analysis reveals that the two-dimensional coordination polymer was fabricated with azide anion and monodeprotonated 2,2′-bypyridine-3,3′-diol as mixed bridge ligands.
