A new compound 1-phenyl-3-methyl-4-(salicylidene hydrazide)-phenylethylene- pyrazolone-5 (PMPeP-SHZ) has been synthesized and characterized by elemental analysis, IR spectrum, MS and single crystal X-ray diffraction. The compound crystallizes in a monoclinic, space group P2(1)/c with cell parameters: a = 10.8275(19) A, b = 24.689(4) A, c = 9.7167(16) A and β = 95.127(4)°, Z = 4, S = 1.097. In the crystal structure, the compound presents in the diketo form. The structure exhibits both intra- and intermolecular hydrogen bonding and the molecules are interlinked through hydrogen bonds forming an infinite 2D network. The fluorescent result shows blue emission at room temperature in solid state.
