(E)-5-{4-[2-(5-Ethylpyridin-2-yl)ethoxy]benzylidene}thiazolidine-2,4-dione

Autor: G. Chakkaravarthi, Kesavan Balakumaran, J. Mosesbabu, Jaya Shree Anireddy

Publikováno v: IUCrData, Vol 3, Iss 1, p x171839 (2018)

In the title compound, C19H18N2O3S, the thiazolidine ring makes dihedral angles of 46.97 (8) and 7.19 (9)° with the pyridine and benzene rings, respectively. The intramolecular structure is stabilized by a weak C—H...S hydrogen bond, which generat
