| Abstract: | The title Schiff base (C8H10N4OS·H_2O. Mr= 230.29) was prepared and its crystal structure was determined by X-ray method. The crystal belongs to the monoclinic system, space group Cc, cell parameters: a = 13.251(3), b = 24.919(6), c = 13.670(3) ?, ( = 101.334(5)(, V = 4425.8(19) ?3, Z = 16, Dc = 1.370 Mg/m3; R = 0.0468, wR = 0.1128. The structure shows a rare chain which is combined by H bond. In addition, the structure of 2-picolinaldehyde Thiosemicarbazone N-oxide is compared with the title compound and is discussed the difference between them. |
