title: 1,2-Bis(4-methyl-benz-yl)diselane.
abstract: The title mol-ecule, C(16)H(18)Se(2), features a diselenide bridge between two 4-methyl-benzyl units, in which the central C-Se-Se-C torsion angle is 88.1 (3)°, while the two Se-Se-C-C fragments assume gauche conformations, with torsion angles of -51.8 (5) and 59.1 (4)°. The dihedral angle between the benzene rings is 78.9 (2)°.
