Aqua­bis­(1,1,1,5,5,5-hexa­fluoro­acetyl­acetonato)[4′-(4-pyrid­yl)-2,2′:6′,2′′-terpyridine]­ytterbium(III) chloride methanol monosolvate monohydrate

The title compound, [Yb(C₅HF₆O₂)₂(C₂₀H₁₄N₄)(H₂O)]Cl·CH₃OH·H₂O, 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 b-axis via inter­molecular hydrogen bonds between the Yb—OH₂ 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.
