Synthesis and Crystal Structure of N,N'-Bis-[(1-phenyl-3-methyl-5-oxo-4-pyrazolinyl)-α-furylmethylidyne]ethylenediimine

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.
