Description
Summary:The title compound, {[Tm(C7H3NO4)(C7H4NO4)(H2O)2]·2H2O}n, is isotypic with the analogous TbIII compound [Li et al. (2009). Acta Cryst. E65, m410]. All interatomic distances and angles and the hydrogen-bond geometries are very similar for the two structures. The refined Flack parameter of 0.49 (2) suggests inversion twinning.
