ABSTRACT: The asymmetric unit of the title compound, [Tm2(C7H6NO2)6(H2O)4]·2H2O, contains three 4-amino-benzoate (4ABA) ligands, two coordinated water mol-ecules, a thulium metal ion, and a water mol-ecule of crystallization. The overall structure of the complex (4ABA-Tm) is in the form of a dimer. In the dinuclear thulium complex, symmetry-relevant TmO8 coordination polyhedra are formed by the O atoms of two chelating 4-amino-benzoate ligands, the O atoms of two non-chelating 4-amino-benzoate ligands, and two water mol-ecules. The Tm-O bond lengths range from 2.216 (3) to 2.471 (3) Å with the Tm⋯Tm separation in the dinuclear complex being 4.7863 (5) Å. The crystal structure features O-H
