Diethyl 2-{[(5-oxo-5H-thio-chromeno[2,3-b]pyridin-7-yl)amino]-methyl-idene}propane-dioate.


ABSTRACT: In the title compound, C(15)H(14)O(2)S, the three fused rings are roughly coplanar, the largest deviation from the mean plane being 0.1285?(13)?Å for the S atom. An intra-molecular N-H?O hydrogen bond generates an S6 ring. In the crystal, inter-molecular C-H?O hydrogen bonds form R(2) (2)(14), R(2) (2)(13) and R(3) (2)(17) ring motifs, building a layer parallel to (100).

In the title compound, C(15)H(14)O(2)S, the three fused rings are roughly coplanar, the largest deviation from the mean plane being 0.1285 (13) Å for the S atom. An intra-molecular N-H⋯O hydrogen bond generates an S6 ring. In the crystal, inter-molecular C-H⋯O hydrogen bonds form R(2) (2)(14), R(2) (2)(13) and R(3) (2)(17) ring motifs, building a layer parallel to (100). ...[more]
