title: 11-(p-Tolylsulfonyl)-8,14,24-trioxa-11,22,23-triazatetracyclo[19.2.1.0.0]tetracosa-1(23),2,4,6,15,17,19,21-octaene.
abstract: In the title compound, C(25)H(23)N(3)O(5)S, the central 1,3,4-oxadiazole ring makes dihedral angles of 35.05 (7), 23.68 (7) and 82.55 (8)°, with the three benzene rings. In the crystal structure, the packing is stabilized by weak non-classical inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into an infinite network.
