ABSTRACT: In the title compound, C(36)H(44)N(4)O(4)S, the dihedral angles between the central thio-phene ring and the pendent oxadiazole rings are 12.7?(2) and 13.7?(2)°, and the dihedral angles between the oxadiazole rings and their adjacent benzene rings are 6.1?(2) and 17.5?(2)°. An intra-molecular C-H?O inter-action may help to establish the conformation.

5-[1-(3,4-Dichloro-phen-oxy)eth-yl]-1,3,4-oxadiazole-2(3H)-thione hemihydrate.

Project description:In the title compound, C(10)H(8)Cl(2)N(2)O(2)S·0.5H(2)O, the atoms in the oxadiazole ring are essentially coplanar (r.m.s. deviation 0.010?Å). The crystal structure is stabilized by inter-molecular N-H?O hydrogen bonds involving the water mol-ecule, which is situated on an a twofold rotation axis, and two organic mol-ecules, leading to a thione tautomer in the solid state. The C atom attached to the oxadiazole ring adopts a typical sp(3) hybridization. The dihedral angle between the mean plane of the benzene ring of the dichloro-phenyl group and the mean plane of the oxadiazole ring is 74.18?(4)°. The crystal structure is stabilized by intermolecular N-H?O and O-H?S hydrogen bonds.

Project description:In the title compound, C(16)H(14)N(2)O(3), the essentially planar 1,3,4-oxadiazole ring [maximum deviation = 0.0021 (11) Å] is inclined at dihedral angles of 8.06 (6) and 11.21 (6)° with respect to the two benzene rings; the dihedral angle between the latter rings is 11.66 (5)°. In the crystal, short inter-molecular C⋯O inter-actions [2.9968 (15) Å] connect adjacent mol-ecules into chains propagating in [203]. The crystal structure is further stabilized by weak inter-molecular C-H⋯π inter-actions.
