摘　　要：A new compound,N,N＇-bis[（1-phenyl-3-methyl-5-oxo-4-pyrazolinyl）-α-furylme-thylidyne]ethylenediimine （（HPMαFP）2en）,has been synthesized and characterized by IR spectra,thermogravimetric analysis and single-crystal X-ray diffraction. The title compound crystallizes in a monoclinic system,space group P21/c with a = 10.7485（11）,b = 7.6972（8）,c = 16.8367（18） ,β = 93.937（2）o,Z = 2,V = 1389.7（3） 3,Dc = 1.340 g/cm3,F（000） = 588.0,μ = 0.091 and S = 1.016. Structural analysis indicates that （HPMαFP）2en exists in an amine-one form. The molecules are well ordered through two intramolecular （N（3）-H（3）···O（1） and C（2）-H（2）···O（1）） and one intermolecular C（3）-H（3）···O（1） hydrogen bonds,leading to the formation of 1D infinite chains. The interactions of these hydrogen bonds contribute to the stabilization of the compound.A new compound,N,N＇-bis[（1-phenyl-3-methyl-5-oxo-4-pyrazolinyl）-α-furylme-thylidyne]ethylenediimine （（HPMαFP）2en）,has been synthesized and characterized by IR spectra,thermogravimetric analysis and single-crystal X-ray diffraction.
