摘要：

<正> Reaction of 2-pyridone, copper acetate and terbium（or yttrium） perchlorate in acetone with the moleratio 6: 2: 1 results in the formation of heteronuclear complex Ln2Cu4L8 （HL）4 （OH）2 （ClO4）4 （H20）102CH3COCH3(Ln = Tb （1）, Y （2）). By recrystallizing （1） in CHCl3 single crystals were obtained and thestructure was determined by four-circle diffractometer. Data showed that the crystal is in space groupC2/m with a=27. 454（9）A, b=13, 608A, c=30. 556（11）A, β=99. 89（3）°, v=11245. 7（7. 5）A3. Thestructure was solved by a combination of Patterson method and Fourier technique. The final R value is0. 103. In the structure, four copper and two terbium ions are bridged by 2-pyridone anions to form anessentially octahedral Cu4Tb2 core. The terbium atoms are each eight-coordinate and the copper atomsare five-coordinate.
