Edited by E. R. T. Tiekink, University of Malaya, MalaysiaIn the structure of the title compound, C 12 H 12 O 3 , the dihydropyran ring is fused with the benzene ring. The dihydropyran ring is in a half-chair conformation, with the ring O and methylene C atoms positioned 1.367 (3) and 1.504 (4) Å , respectively, on either side of the mean plane formed by the other four atoms. The methoxy group is coplanar with the benzene ring to which it is connected [C bCb-O m -C m torsion angle = À0.2 (4) ; b = benzene and m = methoxy], and similarly the aldehyde is coplanar with respect to the double bond of the dihydropyran ring [C dh -C dh -C a -O a = À178.1 (3); dh = dihydropyran and a = aldehyde]. In the crystal, molecules are linked by weak methyl-methoxy C-HÁ Á ÁO hydrogen bonds into supramolecular chains along the a-axis direction.

In the title compound, C 24 H 14 Cl 2 N 2 O 2 S, the 2H-chromene ring system is approximately planar, with a maximum deviation of 0.025 (2) Å . The thiazole 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 chlorophenyl rings. The two chlorophenyl rings show significant deviation from coplanarity, with a dihedral angle between them of 47.69 (8) . The crystal structure features C-HÁ Á ÁCl interactions extending in (100) and propagating along the a-axis direction and weak -interactions [centroid-centroid separation = 3.867 (2) Å ].
