Crystal structure of (Z)-3-{3-(4-chloro-phen-yl)-2-[(4-chloro-phen-yl)imino]-2,3-di-hydro-thia-zol-4-yl}-2H-chromen-2-one.

Abstract

In the title compound, C24H14Cl2N2O2S, the 2H-chromene ring system is approximately planar, with a maximum deviation of 0.025 (2) Å. The thia-zole ring is almost planar, with an r.m.s. deviation of 0.0022 Å, and makes a dihedral angle of 58.52 (7)° with the chromene ring system. The chromene ring system is inclined at angles of 58.3 (1) and 55.39 (9)° with respect to the two chloro-phenyl rings. The two chloro-phenyl rings show significant deviation from coplanarity, with a dihedral angle between them of 47.69 (8)°. The crystal structure features C-H⋯Cl inter-actions extending in (100) and propagating along the a-axis direction and weak π-π inter-actions [centroid-centroid separation = 3.867 (2) Å].
