title: 1,2-Bis(4-ethynylphen-yl)disulfane.
abstract: In the title compound, C(16)H(10)S(2), the S atoms are almost coplanar with the benzene rings to which they are bonded [deviations of 0.092 (1) and 0.022 (1) Å from their respective ring planes]. The benzene rings enclose a dihedral angle of 79.17 (3)°. An intra-molecular C-H⋯S hydrogen bond results in the formation of a five-membered ring. In the crystal structure, mol-ecules are stacked parallel to the a axis direction. π-π inter-actions between benzene rings are present, with a face-to-face stacking distance of 3.622 (10) Å.
