A novel two-dimensional self-assembly network formulated as [K(TSSB)]n (TSSB= taurine-salicylaldehyde Schiff base) has been synthesized via the reaction of salicylaldehyde with taurine at the presence of potassium hydroxide in water-methanol solution,and was structurally characterized by elemental analysis,IR,UV-VIS spectra and X-ray diffraction.It crystallizes in the monoclinic system,space group P21/c with a=20.245(3),b=7.2905(9),c=7.5458(10),β= 94.1920(10)o,V=1110.8(2)3,Mr=267.34,Z=4,Dc=1.599 g/cm3,μ(MoKα)=0.663 mm-1 and F(000)=552.The units of K[TSSB] are linked into a one-dimensional double chain structure via the sulfonic groups from the taurine-salicylaldelyde Schiff base,and such chains are further extended through O-K-O bond interactions resulting in a two-dimensional supramolecular architecture.In the complex,the K(I) ion displays a slightly distorted dodecahedral geometry with an eight-coordination number.

Units of K [TSSB] are linked into a one-dimensional double chain structure via the sulfonic groups from the taurine-salicylaldelyde Schiff base, and such chains are further extended through OKO binding interactions resulting in a two-dimensional supramolecular architecture .In the complex, the K (I) ion displays a slightly distorted dodecahedral geometry with an eight-coordination number.
