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.
