title: 4-{(4-Chloro-phen-yl)[4-(4-methyl-phen-yl)-1,2,3-selenadiazol-5-yl]meth-yl}-4,5,6,7-tetra-hydro-1,2,3-benzoselenadiazole.
abstract: In the title compound, C(22)H(19)ClN(4)Se(2), the mean plane of the non-fused selenadiazole ring forms dihedral angles of 54.20 (16)° and 70.48 (11)°, respectively, with the essentially planar [maximum deviations of 0.025 (5) and 0.009 (2) Å, respectively] methyl-phenyl and chloro-phenyl substituents. The tetra-hydro-1,2,3-benzoselenadiazole group is disordered over two sets of sites with a refined occupancy ratio of 0.802 (5):0.198 (5). In the crystal, weak inter-molecular C-H⋯N inter-actions are observed.
