In the anion of the title compound, (C5H6N)[Dy(C5H4F3O2)4], the central metal ion, Dy3+, is coordinated by four bidentate 1,1,1-trifluoropentane-2,4-dionate (TAA) ligands, forming an approximate square-antiprismatic configuration. The pyridinium cation is connected to the complex ion by an N—H⋯O hydrogen bond and electrostatic interactions in the crystal. There are two kinds of disorder in the structure, one involving rotational disorder of a CF3 group [occupancy ratio 0.560 (15):0.440 (15)] and the other involving an exchange between a CF3 group and CH3 group within a given bidentate ligand (occupancy ratio 0.64:0.36).

A mixture of Dy2O3 (0.186 g) and concentrated hydrochloric (5 mL) was heated and distilled to slight dryness, yielding a crystalline precipitate (DyCl3). Then, the DyCl3 solid was redissolved in 5 mL absolute ethanol, and heated with 10 mL of absolute ethanol solution containing HTAA (0.50 mL) and pyridine (0.32 mL) at about 363 K. The reaction mixture was maintained at ambient temperature for one month until yellow crystals formed.
All F atoms were found to be disordered. There is disorder of the two different types: 1) disorder due to rotational disorder of the CF3 group bonded to a single carbon. F4, F5, and F6 atoms was split into to two sets of positions using restraints on their anisotropic displacement parameters. The major and minor disorder components had refined occupancies of 0.56 (2) and 0.44 (2), respectively; 2) disorder due to exchange of CH3 and CF3 groups on the same ligand. Namely, F10, F11, and F12 as well as related H atoms were modelled over two sets of positions using restraint on their anisotropic displacement parameters. The major and minor disorder components had refined occupancies of 0.64 (1) and 0.36 (1), respectively. In the final
the occupancies of these disordered atoms were fixed to aid convergence. Atoms F11B, F4, F5, F6, F4B, F5B, and F6B were refined anisotropically using 42 restraints (ISOR) and the geometrical parameters of CF3 group were refined using 36 restraints (DFIX and DANG) because of the unacceptable parameters of their ellipsoids and distances between atoms. H atoms attached to C and N were placed in geometrically idealized positions with Csp^2^—H = 0.93, Csp^3^—H = 0.96, Nsp^2^—H = 0.86 Å, and constrained to ride on their carrier atoms, with Uĩso~(H) = 1.2Ũeq~(C & N) and Uĩso~(H) = 1.5Ũeq~(C).Data collection: SMART (Bruker, 2000); cell

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. |

Rare earth-β-diketone complexes have attracted considerable attention in the past decades owing to their important applications as laser (Iwamuro et al., 1997), fluorescent probe (Tsukube & Shinoda, 2002) and NMR reagents (Chu & Elgavish, 1995). As part of our interest in this field, we have been engaged in a major effort directed toward the development of syntheses of new lanthanide-β-diketon complexes.
The structure of the title Dy3+ complex is shown in Fig. 1. It contains an eight-coordinate dysprosium ion bonded to four TAA anions with bidentate chelation, forming the [Dy(TAA)4]- anions. These are connected to pyridinium cations by a N—H···O hydrogen bond. The co-ordination polyhedron may be described as an approximate square antiprism and the two sets of four O atoms (O2, O4, O5, O7) and (O1, O3, O6, O8) form the twisted upper and lower sides respectively. The Dy—O bond lengths are in the range of 2.305 (5)–2.423 (5) Å, average 2.351 (2) Å, which is consistent with other work in literature (Ma et al., 2000; Tian et al., 2009). The average angle of O—Dy—O is 100.25° and the average dihydral angle (C—O—Dy—O) is -10.49°.
