摘要:
Reaction of 2-pyridone, copper acetate and terbium (or yttrium) perchlorate in acetone with the mole ratio 6:2:1 results in the formation of heteronuclear complex Ln2Cu<、sub>4L8 (HL)4 (OH)2 (ClO4)4 (H20)10 2CH3COCH3(Ln=Tb (1), Y (2)).By recrystallizing (1) in CHCl3 single crystals were obtained and the structure was determined by four-circle diffractometer.Data showed that the crystal is in space group C2/m with a=27.454(9)Å, b=13, 608Å, c=30.556(11)Å, β=99.89(3)°, v=11245.7(7.5)Å3.The structure was solved by a combination of Patterson method and Fourier technique.The final R value is 0.103.In the structure, four copper and two terbium ions are bridged by 2-pyridone anions to form an essentially octahedral Cu4Tb2 core.The terbium atoms are each eight-coordinate and the copper atoms are five-coordinate.
