The title complex, [Nd(C₈H₄F₃O₂S)₃(H₂O)₂]·CH₃CN, consists of an Nd^III ion surrounded by three 4,4,4-trifluoro-3-oxo-1-(thiophen-2-yl)but-1-en-1-olate ligands, coordinated through the O atoms, and two water molecules. The Nd—O bond lengths range from 2.372 (2) to 2.513 (2) Å. The metal ion displays a coordination number of eight and a square-antiprismatic coordination geometry. A single uncoordinated acetonitrile molecule is present in the asymmetric unit. Two of the three thiophene rings are disordered, resulting from a 180° rotation with respect to the β-diketonate moiety. The coordinated water molecules act as hydrogen-bond donors towards the acetonitrile N atom and the β-diketonate O atoms.

Related literature

The title complex has been studied for its near-infrared emitting properties and as a standard for near-infrared emission quantum yield measurements, see: Rusakova et al. (1992a ,b ); Voloshin et al. (2000 ). For the Eu^III analog, see: White (1976 ). A similar Nd^III complex with trifluoroacetyl-4-(thiophen2-yl)acetonato ligands but with triphenylphosphine oxide instead of water molecules as the ancillary ligands was described by Leipoldt et al. (1975 ).

Comment top

For determining emission efficiencies of sensitized lanthanide luminescence in the NIR region of the spectrum, a Nd^III complex with 4,4,4-trifluoro-3-oxo-1-(thiophen-2-yl)but-1-en-1-olate (TTA) (Scheme 1) is used as a standard (Rusakova et al., 1992a). We synthesized the complex and isolated X-ray quality single crystals. The structure shown in Figure 1 was obtained. The Nd^III is surrounded by three TTA ligands, coordinated through the oxygen atoms, and two water molecules. Two TTA ligands are in the same plane while the remaining one is almost perpendicular to that plane with an angle of 87.6°. A single uncoordinated acetonitrile molecule crystallized within the asymmetric unit. Two of the three thiophene rings are disordered, as seen for many structures involving thiophene moieties. Modeling the disorder gives two different positions for the thiophene rings, where they are rotated 180° around the C—C bond to the beta-diketone. The occupancy factors for both disordered rings are 59 and 61% for the major component. Figure 2 shows the coordination polyhedron around the Nd^III, which can be described as a slightly distorted square antiprism. The Nd^III—O bond distances are in the range 2.372 (3)–2.513 (3) Å with the TTA ligands displaying the shorter bond lengths. These distances compare well with a similar structure of Nd^III with TTA reported by Leipoldt et al. (1975), with the formula [Nd(TTA)₃(TPPO)₂] (TPPO=triphenylphosphine oxide). In this complex the two water molecules are replaced by two TPPO ligands. The final complex has a similar coordination environment around the Nd^III ion with Nd^III—O bond distances in the range 2.397–2.496 Å, with the shorter bond distances corresponding to the TPPO ligands.

Hydrogen bonding interactions support the packing structure of the complex and are shown in Figure 3 with blue dashed lines. Interactions exist between the water molecule O—H donors and the acetonitrile N and beta-diketonato O acceptors with D···A distances in the range 2.803 (3)–2.893 (4) Å. A search of similar interactions in the Cambridge Structural Database yields 194 results with a range of interaction distances between 2.597 and 3.040 Å and an average of 2.834 Å. The reported distances are slightly longer than the distances in the complex discussed here. An isostructural Eu(III) complex has also been reported by White (1976). Due to slow decomposition of the crystals of the Eu(III) complex the data reported were poor, but the weak hydrogen bonding interactions were shown to be in the range D···A = 2.9–3.0 Å.

The title complex has been studied for its near-infrared emitting properties and as a standard for near-infraed emission quantum yield measurements, see: Rusakova et al. (1992a,b); Voloshin et al. (2000). For the Eu(III) analog, see: White (1976). A similar Nd^III complex with trifluoracetyl-4-(thiophen2-yl)acetonato ligands but triphenylphosphine oxide) instead of water molecules as the ancillary ligands was described by Leipoldt et al.

Experimental top

The title compound was synthesized by a previously reported procedure (Voloshin et al. 2000). Crystals were isolated from a saturated solution of acetonitrile and water (v/v = 1:5) upon standing at room temperature.

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.
