Poly[bis(μ4-benzene-1,4-dicarboxylato)(μ4-succinato)diterbium(III)]

Abstract

In the title compound, [Tb2(C4H4O4)(C8H4O4)2]n, the coordination around each Tb atom is distorted square-antiprismatic. The benzene-1,4-dicarboxylate and succinate anions bridge the antiprisms, forming a three-dimensional network. The succinate anion is located on a centre of inversion. The structure is isomorphous with the Dy, Gd, Er and Nd complexes.
