Poly[(μ₄-benzene-1,3,5-tricarboxyl­ato)bis­(N,N-dimethyl­acetamide)­terbium(III)]

The title compound, [Tb(C₉H₃O₆)(C₄H₉NO)₂], shows a rare-earth three-dimensional metal-organic framework structure. In this complex of an eight-coordinated Tb³⁺ ion, the asymmetric unit contains one benzene-1,3,5-tricarb­oxy­lic ligand and two coordinated dimethyl­acetamide mol­ecules. Each Tb³⁺ ion is coordinated by six O atoms from four carboxyl­ate groups of the benzene-1,3,5-tricarb­oxy­lic ligands and two O atoms from two terminal dimethyl­acetamide mol­ecules.
