The title compound, [Yb(C5HF6O2)2(C20H14N4)(H2O)]Cl·CH3OH·H2O, adopts an eight-coordinated geometry around the YbIII 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.

The molecular design of multidentate ligands is crucial to determining structures and functions of the resulting coordination compounds and metallo-supramolecular systems. Specifically, a tetradentate ligand 4'-(4-pyridyl)-2,2':6',2"-terpyridine (pytpy) provides a unique structural feature as a bridging ligand where two different coordination donors, the tridentate terpyridyl and monodentate pyridyl moieties, are both associated with metal coordination. Herein we report an unusual bridging mode of pytpy in a one-dimensional metallo-supramolecular system as exemplified with an X-ray crystal structure of compound (I), where the monodentate pyridyl arm in pytpy is now bound to the neighboring molecule via intermolecular hydrogen bonding to form a one-dimensional supramolecular chain. Compound (I) consists of a monocationic complex [YbIII(pytpy)(hfac)2(H2O)], a Cl- anion, and lattice solvents, CH3OH and H2O. The YbIII center is surrounded by three N donors from pytpy and five O donors from two hfac chelates and one aqua ligand completing the 8-coordinate geometry as shown in Figure 1. Among structurally determined YbIII complexes containing a single terpyridine ligand, the coordination number 8 is rather unusual and 9- and 10-coordination is more commonly observed (Hayashi et al., 1998; Ahrens et al., 2002; Fukuda et al., 2002; Przychodzen et al., 2007; Li et al., 2007; Xu et al., 2009; Stojanovic et al., 2010). The 8-coordination around lanthanide(III) ions are seen, for example, in [LnIII(Trop)4]- [Trop = tropolonene (2-hydroxycyclohepta-2,4,6-trienone)] (Zhang et al., 2007a). In compound (I), the Yb—N(pytpy) lengths vary from 2.434 (3) to 2.464 (3) Å and the Yb—O(hfac) lengths from 2.262 (3) to 2.334 (3) Å; these values compare well with those observed in complexes containing the [YbIII(tpy)(hfac)3] entity (Li et al., 2007; Xu et al., 2009). There is a hydrogen-bonding interaction with the chloride anion with an O5···Cl1i (symmetry code: (i) 1 + x, y, z) distance of 3.054 (3) Å and an O6···Cl1 distance of 3.102 (3) Å. An additional hydrogen-bonding interaction is seen between the N atom of the dangling pyridyl group and the aqua ligand in the neighboring molecule with an O5···N4ii (symmetry code: (ii) x, 1 + y, z) distance of 2.686 (4) Å to form one-dimensional supramolecular chains of [Yb(pytpy)(hfac)2(H2O)]+ units running along the b-axis. Similar hydrogen bonded one-dimensional networks including pytpy moieties have been also reported (Beves et al., 2007b; Beves et al., 2008).

Experimental top

An ethanol solution (50 ml) of pytpy (600 mg, 1.94 mmol) Hhfac (1.21 g, 5.92 mmol), and YbCl3.6H2O (760 mg, 1.94 mmol) was stirred for 30 min at room temperature. After evaporation, the residue was recrystallized from CH3OH/water to give (I) as colorless crystals. Elemental analysis of the compound that was dried by vacuum pumping overnight at room temperature reveals the loss of the solvent molecules of crystallization (H2O and CH3OH). Transparent needle-shaped single crystals of compound (I) suitable for X-ray diffraction analysis were obtained by slow evaporation of a CH3OH/water (95:5, v/v) solution in a few days. Yield: 637 mg, 0.67 mmol (35%). Analysis: calculated for C30H18ClF12N4O5Yb ([Yb(pytpy)(hfac)2(H2O)]Cl): C 37.89, H 1.91, N 5.89%; found: C 37.60, H 1.96, N 5.92%. IR (KBr pellet): 1603, 1664, 3031, 3410 cm-1. UV-vis (CH3OH) λmax/nm (ε/M-1cm-1): 241 (41,300), 285 (34,300). ESI-TOF-MS (CH3OH): m/z 898.39 (calcd: 898.04 for [M–2H2O–CH3OH–Cl-]+).

Refinement top

H atoms except those of water were placed in geometrically idealized positions and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C—H) or 1.5Ueq(O—H).

The lattice water shows positional disorder which is modeled as two oxygen atoms, O7A and O7B, with site occupancies of 0.58 and 0.42, respectively. The O7A—O7Aiii (symmetry codes: (iii) 1 - x, 2 - y, 1 - z) distance was restrained to 2.56 (1) Å using the DFIX command of the program SHELXTL (Sheldrick, 2008) because of a strong correlation between positional parameters of the two components of the disorder.

H atoms attached to O5 (H5A and H5B) and lattice water (H7A, H7B, H7C, and H7D) were found in a difference Fourier map. The O—H and H—H distances within the water molecules were restrained to 0.83 (7) Å) and 1.35 (8) Å , respectively, by using the DFIX command for a stable refinement. Hydrogen atoms on the lattice water were not included in the structure factor calculation.

Four trifluoromethyl groups were found to show disorder. The geometries of the trifluoromethyl groups were constrained by using the SAME command. Anisotropic displacement parameters of the pairs of overlapping disordered atoms of the major and minor components of the disorder were made equal using the EADP constraints. The final occupancies of the disordered CF3 groups were found to be 0.81:0.19, 0.76:0.24, 0.90:0.10, and 0.86:0.14 for (C21A, F1A, F2A, F3A)/(C21B, F1B, F2B, F3B), (C25A, F4A, F5A, F6A)/(C25B, F4B, F5B, F6B), (C26A, F7A, F8A, F9A)/(C26B, F7B, F8B, F9B), and (C30A, F10A, F11A, F12A)/(C30B, F10B, F11B, F12B), respectively.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
