3-(Thiazol-2-ylamino)isobenzofuran-1(3H)-one

Abstract

The crystal structure of the title compound, C11H8N2O2S, is stabilized by one N-H center dot center dot center dot N and two C-H center dot center dot center dot O intermolecular hydrogen bonds and also by three C-H center dot center dot center dot pi interactions. The C-H center dot center dot center dot O hydrogen bonds generate R-4(4)(26) ring motifs and the N-H center dot center dot center dot N and one of the C-H center dot center dot center dot O hydrogen bonds generate R-4(3)( 26) ring motifs. The phthalide ring system of the molecule is almost planar and forms a dihedral angle of 74.84 ( 9)degrees with the thiazole ring.
