The title complex was synthesized by reaction of 2-hydroxypyridine, Tb(ClO4)3 ·6H2O and Co(CH3COO)2·2H2O in CH3CN solution. The crystal of [Tb(CH3COO)3·2H2O]2 belongs to triclinic with space group P1. The unit cell parameters are a = 8.870(4)A, b = 9.247(1) A , c=10.586(1)A, α = 65.13(1)°?, β = 64.43(2)°, r = 62.16(4)A, V=665.97A3, Z=1,F(000) = 394. The Tb atoms are connected through one pair of u2-bridging carboxylic acid groups to form a dimer molecule. Each Tb atom is coordinated by nine oxygen atoms. The polyhedron takes are onecapped square antiprism arrangement.
