Coordination compound of Cu(II) with aminoguanydine sulfate was obtained and its structure determined by X-ray diffraction method. Found that 2[Cu(C₂N₈H₆)₂SO₄]*H₂O crystallizes in monoclinic space group P2₁/c, a=14.188(4), b=5.637(1), c=14.079(4), b=97.5deg., d=1.68g/cm₃, Z=4, R=0.085. The special positions for two Cu²⁺ ions having planar-square coordination are discovered. Planar aminoguanydine molecules bonded to metal through nitrogen atoms and hydrogen-bonded to both sulfate ion and H₂O. The positive charges of protonized aminoguanydine infive-membered rings are delocalized.
