The asymmetric unit of the title dichloro-methane hemisolvate, C(24)H(33)N(5)S·0.5CH(2)Cl(2), comprises an adamantan-yl/triazole derivative and half a CH(2)Cl(2) mol-ecule of crystallization; the latter is disordered about a twofold axis of symmetry. The piperazine ring has a chair conformation and the two N-bound substituents occupy equatorial positions. The piperazine residue is almost normal to the triazole ring [N-N-C-N torsion angle = -79.9 (3)°] so that to a first approximation, the mol-ecule has an L-shape. Linear supra-molecular chains parallel to [001] are formed via C-H⋯S inter-actions. Two such chains are linked into a double chain via C-H⋯Cl inter-actions involving the disordered CH(2)Cl(2) mol-ecules of solvation.
