(E)-6-(4-Chlorophenyl)-4-[(2-cyano-3-phenylallyl)sulfanyl]-2,2-difluoro-3-phenyl-1,3,2-oxazaborinin-3-ium-2-uide

In the title compound, C25H18BClF2N2OS, the characteristic B—N and B—O bond lengths are 1.571 (3) and 1.458 (3) Å, respectively. The phenyl rings form dihedral angles of 83.1 (1) and 64.6 (1)° with the chlorophenyl ring. In the crystal, weak C—H⋯N, C—H⋯F, C—H⋯π and π–π interactions [centroid–centroid distances 3.877 (6) Å between the chlorophenyl rings of neighbouring molecules] held molecules together, forming ladders along the b axis.
