| Summary: | The asymmetric unit of the title compound, [Nd(C9H3O6)(C2H6OS)2]n, contains one Nd3+ ion, one benzene-1,3,5-tricarboxylic ligand and two coordinating dimethyl sulfoxide molecules. The Nd3+ ion is coordinated by six O atoms from four carboxylate groups of the benzene-1,3,5-tricarboxylate ligands and two O atoms from two dimethyl sulfoxide molecules. The metal-organic cluster formed upon symmetry expansion of the asymmetric unit consists of two metal atoms and four benzene-1,3,5-tricarboxylate groups, creating a paddle-wheel-type building block arrangement. The remaining coordination sites are occupied by additional benzene-1,3,5-tricarboxylate groups and dimethyl sulfoxide molecules, forming a three-dimensional polymeric rare earth metal-organic framework structure.
