The crystal and molecular structure of benzylidenimine disulfide has been determined. Crystals are monoclinic with space group P21/c, Z = 4, a = 12.93(2), b = 5.554(9), c = 20.46(3) Å, and β = 112.5(2)°. A full matrix least squares refinement on 2304 unique reflections of positive intensity measure collected on a [Formula: see text] Automatic diffractometer produced a conventional R of 0.029. The molecular geometry is very similar to that in the corresponding tetra- and trisulfides with a fairly short sulfur–sulfur bond length of 2.033(2) Å and a fairly long sulphur–nitrogen bond length of 1.690(3) Å.
