Aqua-bis-(1,1,1,5,5,5-hexa-fluoro-acetyl-acetonato)[4'-(4-pyrid-yl)-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.
