Crystal structure of oxadiarg­yl

In the title compound {systematic name: 5-tert-butyl-3-[2,4-di­chloro-5-(prop-2-yn­yloxy)phen­yl]-1,3,4-oxa­diazol-2(3H)-one}, C(15)H(14)Cl(2)N(2)O(3), which is an oxa­diazo­lone herbicide, the dihedral angle between the planes of the oxa­diazo­lone and benzene rings is 65.84 (6)°. In the crystal, weak inter­molecular Cl⋯Cl [3.3600 (7) Å] short contacts link adjacent mol­ecules, forming chains along the b-axis direction. These chains are linked by C—H⋯O, C—H⋯N and C—H⋯Cl hydrogen bonds, generating a three-dimensional network. Weak C—H⋯π inter­actions are also present.
