Abstract

The derivatives of 4-hydroxychalcones were synthesized and characterized by infrared and 1H NMR spectral studies. The grown crystal was further characterized by single crystal x-ray diffraction studies. The crystal structure of (2E)-3-(4-hydroxyphenyl)-1-phenylprop-2-en-1-one was determined using single crystal x-ray diffraction. The compound crystallizes in orthorhombic crystal class in the space group P212121 with cell parameters a=5.3738(4) Å, b=12.9239(10) Å, c=17.1310(14) Å, Z=4 and V= 1189.76 Å3. The conjugated compound is slightly twisted with a dihedral angle of 25.00° between the benzene and hydroxyphenyl ring. Differential scanning calorimetric studies shows that the crystal is stable up to 186 oC.
