Crystal structures of 3-halo-2-organochalcogenylbenzo[b]chalcogenophenes.

ABSTRACT: The structure of the title compounds 3-bromo-2-(phenyl-sulfan-yl)benzo[b]thiophene (C₁₄H₉BrS₂; 1), 3-iodo-2-(phenyl-sulfan-yl)benzo[b]thio-phene (C₁₄H₉IS₂; 2), 3-bromo-2-(phenyl-selan-yl)benzo[b]seleno-phene (C₁₄H₉BrSe₂; 3), and 3-iodo-2-(phenyl-selan-yl)benzo[b]seleno-phene (C₁₄H₉ISe₂; 4) were determined by single-crystal X-ray diffraction; all structures presented monoclinic (P2₁/c) symmetry. The phenyl group is distant from the halogen atom to minimize the steric hindrance repulsion for all structures. Moreover, the structures of 3 and 4 show an almost linear alig
