Crystals of HTmP2O7·3H2O were prepared via a soft chemistry route. Its crystal structure was solved from single-crystal diffraction data. In its lamellar structure, edge-sharing polyhedra of eightfold coordinated Tm(III) form chains along [010]. These chains are joined in turn to each other using pyrophosphates O-P-O bridges. A network of O –H…O hydrogen bonds reinforces the cohesion of the structure. The IR spectrum of HTmP2O7·3H2O is interpreted on the basis of characteristic vibrations of PO3 group, POP bridge, and in addition, H2O. The optical properties of HTmP2O7·3H2O were analysed w ith UV–Vis.
