摘　　要：A new cobalt-sodium coordination polymer [CoNa（C_9H_9N_3O_2S）_2·H_2O]_2·C_2H_3N·H_2O（1） has been synthesized with cobalt chloride,2-（2-hydroxy-3-methoxybenzylidene）hydrazinecarbothio amide（L） and sodium hydroxide.It crystallizes in the triclinic space group P1,with a = 9.972（4）,b = 10.923（4）,c = 13.489（5） ？,α = 108.005（10）,β = 92.728（10）,γ = 93.16（1）o,V = 1392.0（9） ？~3,Mr = 1151.95,Dc = 1.374 g/cm^3,Z = 2,F（000） = 592,the final GOOF = 1.126,R = 0.1091 and wR = 0.2412.Each unit molecule consists of two cobalt ions and two sodium ions bridged by four 2-（2-hydroxy-3-methoxybenzylidene）hydrazinecarbothio amide anions.The coordination environment of Co ion is CoO_2N_2S_2,giving a distorted octahedral geometry and the Na（1） ion is NaO_4N,giving a distorted square pyramidal geometry.The results show that 1 shows one strong intense fluorescence emission wavelength of 429 nm with an excitation wavelength of 376 nm,and the electron transfer of 1 is irreversible in electrode reactions.
