Abstract: A series of N-aroyl-N'-arylselenoureas(2a—2l) were synthesized at room temperature under phase transfer catalysis conditions by using polyethylene glycol-400 as the catalyst and the structure of compound 2a was confirmed by X-ray crystallographic analysis. In the crystal, compound 2a was assembled to a three-dimensional supramolecular structure by intermolecular hydrogen bonds. The crystal belongs to the monoclinic crystal system, P21/c space group with a=0.607 1(8) nm, b=2.605(3) nm, c=0.918 9(12) nm, β=92.43(2)°, V=1.452(3) nm3, Z=4, Dc=1.525 g/cm3; F(000)=672, μ=2.589 mm-1.
