Abstract: 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)Å, b= 9.247(1)Å, c=10.586(1)Å, α = 65.13(1)°, β = 64.43(2)°, r = 62.16(4)Å, V=665.97Å3, 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. |
