Silver（I） complex with 3,6-bis（2-pyridylthio）pyridazine, {[Ag2（C,4H10N,S2）3]n＇4.5nH20-2nNO3-}（1）, has been prepared and characterized by IR, elemental analysis and single-crystal X-ray diffraction analysis. Complex 1 is a novel two-dimensional honeycomb-like network coordination polymer with （6, 3） topology, and the silver（I） centres exhibit trigonal coordination geometry. It crystallized in Trigonal, space group R-3, with a=15.555 （3）A, b =15.555 （3） A, c=42.587（8）A, α=β=90°, γ=120°, Z=6, V=892 4（3）A3, R1=0.064 5 and wR2=0.213 3. The 2-D layers stack to form honeycomb-like 1-D channels along c-axis. The cyclic voltammetry measuring of complex 1 shows that the redox couple is quasi-reversible redox reaction.
