ABSTRACT
Two thio-chromene com-pounds containing Br and F atoms, namely 2-(2-bromo-5-fluoro-phen-yl)-8-eth-oxy-3-nitro-2H-thio-chromene (C17H13BrFNO3S, A) and 2-(2-bromo-5-fluoro-phen-yl)-7-meth-oxy-3-nitro-2H-thio-chromene (C16H11BrFNO3S, B), were prepared via the condensation reaction between 2-mer-capto-benzaldehyde and nitro-styrene derivatives. In both com-pounds, the thio-chromene plane is almost perpendicular to the phenyl ring. In the structure of A, mol-ecules are assembled via π-π stacking and C-Hâ¯O and C-Fâ¯π inter-actions. In the crystal packing of B, mol-ecules are linked by C-Hâ¯F, C-Hâ¯O, C-Hâ¯π and π-π inter-actions.
