A novel coordination polymer [(C10H16N)2(Pb2I6)· 2DMF· H2O]n (C10H16N=N-butyl-2-Methy-Pyridinium) was syn thesized by the reaction of Pb(NO3)2 with C6H10NI at room temperature in DMF solvent and structurally character ized by means of X-ray single diffraction. The title compound crystallizes in triclinic system, space group P1 with a=1.123 7(2) nm, b=1.253 30(16) nm, c=0.808 00(12) nm, α=102.523(4)°, β=92.475(5)°, γ =95.712(10)°, V=1.102 9(3) nm3, Z=1, Dc=2.470 Mg·m-3, F(000)=738, chemical formula C26H48N4O3Pb2I6 and Mr=1 640.46,μ(MoKα)=11.849 mm-1, the final R=0.057 8 and wR=0.166 5 for 3 716 observed reflections with I ＞ 2o(I). The title com pound consists of cations ([(C10H16N)+] and anion chain(PbI3-),they are combined by static attracting forces in the crystal. DMF and H2O locate between the organic and inorganic moiety.
