3-Benzyl-1-butylimidazo[1,2-a]benzothieno[3,2-d]pyrimidine-2,5(1H,3H)-dione
In the crystal structure of the title compound, C(23)H(21)N(3)O(2)S, all ring atoms of the imidazo[1,2-a]benzothieno[3,2-d]pyrimidine system are essentially coplanar and the phenyl ring is twisted with respect to it [dihedral angle = 72.60 (9)°]. The crystal packing is mainly governed by C—H⋯π hydro...

Sumario: | In the crystal structure of the title compound, C(23)H(21)N(3)O(2)S, all ring atoms of the imidazo[1,2-a]benzothieno[3,2-d]pyrimidine system are essentially coplanar and the phenyl ring is twisted with respect to it [dihedral angle = 72.60 (9)°]. The crystal packing is mainly governed by C—H⋯π hydrogen bonds and intermolecular π–π interactions, with interplanar distances of 3.54 (1) and 3.56 (1) Å, and with distances between adjacent ring centroids of 3.72 (1) and 3.80 (1) Å. The three terminal C atoms of the butyl group are disordered over two positions; the site occupancy factors are ca 0.6 and 0.4. |
