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 H-1 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) angstrom, alpha = 62.213(2)degrees, beta = 71.266(2)degrees, gamma = 88.014(3)degrees, Z = 1, V = 1011.0(2)angstrom(3) . The intramolecular N-H center dot center dot center dot 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 center dot center dot center dot O hydrogen bonds between N-H and the oxygen atom of DMF in the title compound, which help to assemble into supramolecular structure.
