摘　　要：A supramolecular compound（H2en）2[Cu（en）2（H3O）2][Mo8O28]（en=ethylenediamine） was hydrothermally prepared and confirmed by elemental analysis and TG analysis.Single-crystal X-ray analysis reveals that the crystal crystallizes in the triclinic system,space group P1 with a=9.4635（4）,b=9.8645（5）,c=10.9794（5）A,α=69.2050（10）,β=72.3730（10）,γ=78.4510（10）o,Mr=1559.55,V=908.24（7）A^3,Z=1,Dc=2.851 g/m^3,F（000）=749,μ=3.350 mm^-1,S=1.000,the final R=0.0217 and wR=0.0567.The compound consists of（H2en）^2＋,[Mo8O28]^8-anion and [Cu（en）2（H3O）2]^2＋ cations and constructs a 3D supramolecular structure through hydrogen bonds between the nitrogen atoms from en of [Cu（en）2（H3O）2]^4＋ fragments and the terminal oxygen atoms from the [Mo8O28]^8-polyoxoanions.The electrochemical behavior of this compound has been studied in detail based on a solid bulk modified carbon paste electrode of compound（CPE）.A supramolecular compound（H2en）2[Cu（en）2（H3O）2][Mo8O28]（en=ethylenediamine） was hydrothermally prepared and confirmed by elemental analysis and TG analysis.Single-crystal X-ray analysis reveals that the crystal crystallizes in the triclinic system,space group P1 with a=9.4635（4）,b=9.8645（5）,c=10.9794（5）A,α=69.2050（10）,β=72.3730（10）,γ=78.4510（10）o,Mr=1559.55,V=908.24（7）A^3,Z=1,Dc=2.851 g/m^3,F（000）=749,μ=3.350 mm^-1,S=1.000,the final R=0.0217 and wR=0.0567.The compound consists of（H2en）^2＋,[Mo8O28]^8-anion and [Cu（en）2（H3O）2]^2＋ cations and constructs a 3D supramolecular structure through hydrogen bonds between the nitrogen atoms from en of [Cu（en）2（H3O）2]^4＋ fragments and the terminal oxygen atoms from the [Mo8O28]^8-polyoxoanions.The electrochemical behavior of this compound has been studied in detail based on a solid bulk modified carbon paste electrode of compound（CPE）.
