A new cobalt-sodium coordination polymer vertical bar CoNa(C9H9N3O2S)2 center dot H2O vertical bar(2)center dot C2H3N center dot H2O (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 P (1) over bar, with a = 9.972(4), b = 10.923(4), c = 13.489(5) angstrom, alpha = 108.005(10), beta = 92.728(10), gamma = 93.16(1)degrees, V = 1392.0(9) angstrom(3), M-r = 1151.95, D-c = 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 CoO2N2S2, giving a distorted octahedral geometry and the Na(1) ion is NaO4N, 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.
