Synthesis,crystal structure,and comparative study of a new organic material 3,4-diaminobenzophenone semihydrate

The new organic 3,4-diaminobenzophenone semihydrate (34abph) is grown by slow evaporation method. the compound crystallizes in the monoclinic space group: c2. the unit cell dimensions are a = 28.703 (8) å,b = 4.722 (2) å,c = 8.7076 (10) å,and β = 99.40 (2)° with z = 2. the crystal structure analysis reveals that the c13h12n 2o molecules chains are organized into a double ribbon in the (b,c) plane. the structural components interact by n-ho and o-ho hydrogen bonds,building up a two-dimensional network. the presence of functional groups in the molecular structure is confirmed by the fourier transform infrared (ft-ir) spectroscopy. thermogravimetric analysis (tga) confirms the presence of the water molecule. © 2013 tarek ben rhaiem et al.
