2-(4-tert-Butylphenyl)-5-{3,4-dibutoxy-5-[5-(4-tert-butylphenyl)-1,3,4-oxadiazol-2-yl]-2-thienyl}-1,3,4-oxadiazole
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.

In the title compound, C(19)H(20)N(2)O, the dihedral angles between the 1,3,4-oxadiazole ring and the pendant 4-tert-butyl-phenyl and 4-methyl-phenyl rings are 12.53 (17) and 2.14 (17)°, respectively. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains.
متن کامل5-tert-Butyl-2-[5-(5-tert-butyl-1,3-benzoxazol-2-yl)-2-thienyl]-1,3-benzoxazole
The title compound, C(26)H(26)N(2)O(2)S, was prepared by the reaction of thio-phene-2,5-dicarboxylic acid and 2-amino-4-tert-butyl-phenol. One of the tert-butyl groups is disordered over two conformations, with occupancies of 0.539 (1) and 0.461 (2). The two 1,3-benzoxazole rings are almost planar, with dihedral angles of 0.83 (18) and 1.64 (17)° between the five- and six-membered rings. The th...
