Abstract
The title compound, C28H25N3OS, has has been characterized by single-crystal X-ray diffraction. It crystallizes in the triclinic system, space group P1 (No. 2), a = 10.058(3), b = 10.318(3), c = 13.560(3)Å, α = 98.694(19), β = 107.418(19), γ = 107.069(19)°; V = 1238.7(5)Å3 and Dx = 1.211 Mg m-3, Z = 2. The structure was refined to an R-value of 0.0573 for 1749 observed reflections using three-dimensional X-ray diffraction data. The pyrimidine ring is slightly distorted from planarity, with the maximum deviation from the mean plane of -0.072(4)Å for atom C1. The molecules contain four rings that are not coplanar. The dihedral angles between three benzene rings are 44.6(3), 77.6(2) and 87.4(2)°. The three benzene rings form dihedral angles of 31.4(2), 57.4(2) and 61.2(2)° with the pyrimidine ring. No classic hydrogen bonds were found.
