Synthesis, Crystal Structure, and Comparative Study of a New Organic Material 3,4-Diaminobenzophenone Semihydrate

Abstract EN

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 C13H12N2O molecules chains are organized into a double ribbon in the (b,c) plane.

The structural components interact by N–H⋯O and O–H⋯O 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.
