N-[1-(2-Methyl-1-methylcarbamoyl-propylcarbamoyl)-2,3-diphenyl-cyclopropyl]-ben- zamide, C29H31N3O3, has been synthesized and characterized by IR, ^1H NMR, ^13C NMR and singlecrystal X-ray diffraction. The crystal is of orthorhombic, space group P212121 with a = 11.0855(11), b = 18.7756(19), c = 24.434(2)A, V = 5085.5(9)A^3, Z = 8, Mr = 469.57, Dc = 1.227 g/cm^3, λ = 0.71070 A,μ(MoKα) = 0.080 mm^-1, F(000) = 2000, the final R = 0.0579 and wR = 0.1111 for 4569 observed reflections with I 〉 2σ(I). The N-H and oxygen atom are involved in intermolecular hydrogen bonds which link the molecules into a one-dimensional chain. 展开更多
