Abstract: Aseries of 2-phenyliminothiazolidines has been successfully synthesized; and 2-(2-methylphenyl)iminothiazolidine(Ⅰa) and 2-(4-methylphenyl) iminothiazolidine(Ⅰb) have been selected to determine their crystal structures by X-ray diffraction technique, from their molecular graph of it is shown that double bond at 2-carbon atom of the heterocycle is all extro-cyclic at the crystal state, and there are two main plaines in Ⅰa and Ⅰb. But in Ⅰa, the angle between the planes is 61.4° and in Ⅰb the angle is about 41.4°. And so there is a strong conjugative effect in Ⅰb than in Ⅰa. So it is thought that the difference in fungicidal activies between 2-substitutedphenyl compounds(Ⅰa) and 4-substitutedphenyl compounds(Ⅰb) is due to their space factors.

Key words: Crystal structure, 2-Phenyliminothiazolidine, Conjugated effect, Fungicidal activity, Space factor
