摘　　要：The complex ·(ClO4)2 was synthesied and characterized by X ray diffraction. X ray diffraction result for the single crystal showed that the crystal belongs to triclinic, space group , a=0.8123(2),b=1.1024(2), c=1.8646(4)nm,α=102.30(3)°,β=91.00(3)°,γ=99.69(3)°,V=1.6056(6)nm3,Z=2,Dc=1.494g·cm-3. The thermal decomposition of (ClO4)2 occurred in a three steps pattern. The reaction mechanism of the first step decomposition was deduced as n(1-α)[-ln(1-α)](n-1)/n with the activation energy of 130kJ·mol-1.The complex [ Mn (bipy) (3)] (.)
