Synthesis and Crystal Structure of N , N ′ -( p -phenyl)-bis-(p-nitro)benzoylthiourea

N, N′ -(p-phenyl)-bis-(p-nitro)benzoylthiourea was synthesized and characterized by elemental analysis as well as IR and 1H NMR spectroscopy. The crystal structure of the title compound was determined by single crystal X-ray diffraction. It was crystallized in triclinic space group of P-1, a = 8.1084(12), b = 11.9185(13), c = 12.6061(15) A, α = 62.213(2)°, β = 71.266(2)°, γ = 88.014(3)°, Z = 1, V = 1011.0(2)A 3 . The intramolecular N-H · · · O hydrogen bonding interactions between the N-H and the oxygen atom of C═ O groups suport N, N′ -(p-phenyl)-bis-(p-nitro)benzoylthiourea framework. the solvent DMF molecules are accommodated in the framework by intermolecular N-H · · O hydrogen bonds between N-H and the oxygen atom of DMF in the title compound, which help to assemble into supramolecular structure.
