The title compound, [Yb(C 5HF 6O 2) 2(C 20H 14N 4)(H 2O)] Cl·-CH 3OH·H 2O, adopts an eight-coordinated geometry around the Yb III atom consisting of a 4'-(4-pyridyl)-2,2': 6',2''-terpyridine (pytpy) ligand, two 1,1,1,5,5,5-hexafluoroacetylacetonate (hfac) anions and an aqua ligand. In the solid state, the compound forms supramolecular chains running along the baxis via intermolecular hydrogen bonds between the Yb-OH 2 unit and the N-atom donor of the 4-pyridyl pendant of pytpy, with an O ··· N distance of 2.686(4) Å. A chloride counter-anion and lattice methanol and water solvent molecules occupy a hydrophilic columnar space along the coordination chains. O-H ··· Cl hydrogen bonds occur. The two water molecules and the four trifluoromethyl groups are disordered over two sets of sites, each with different occupancy ratios.
