[ Pb (DNI) 2 ( H2 O) 4 ] was prepared by mixing the aqueous solution of sodium 2,4-dinitroimidazolate and lead nitrate. The single crystal structure of [ Pb (DNI)2 (H2 O)4 ] has been determined by single crystal diffraction analysis. The crystal monoclinic space group Cc with crystal parameters of α = 6.517(3) ×10^-1 nm,b =17.131(6) ×10^-1 nm,c=14.082(7) ×10^-1 nm,α= 90.00(3) °,β=97.80(4)°, γ=90.00(4) °,V=1 557.5(12) ×10^-3 nm^3,Z=4,Dc=2.531 g/cm^-3,μ=11.001 mm^-1,F(000) = 1 120. The final deviation factor R is 0.022 6. According to the IR spectra analysis,the element analysis and the X-ray diffraction analysis, the chemical component of the 2,4-DNI lead complex is C6 H10O12 N8Pb and its formula is [ Pb(DNI)2 ( H2O)4 ].
