In the title compound, [Lu(C7H7)3(C4H8O)2] (1), the Lu ion is coordinated by three benzyl and two tetrahydrofuran ligands. Two of the benzyl groups are bonded in a classical η1-fashion through the methylene via the ipso-carbon atom of the benzyl ligand in addition to bonding through the methylene C atom, resulting in a modified trigonal–bipyramidal coordination geometry about the Lu center.

1. Chemical context
The chemistry of σ-bonded rare-earth metal (RE) hydrocarbyl complexes has a long and rich history (Zimmermann & Anwander, 2010), with the compounds being versatile synthetic precursors and involved in important polymerization and various catalytic transformations. Lappert & Pearce (1973) reported the synthesis of the first well-defined homoleptic trialkyl compounds utilizing neopentyl and trimethylsilylmethyl ligands, [RE(CH2tBu)3(THF)2] and [RE(CH2SiMe3)3(THF)2] (RE = Sc, Y). More recently, the benzyl ligand (CH2Ph) has been successfully employed to provide access to a wide range of [RE(CH2Ph)3(THF)x] (x = 2, 3) compounds (Bambirra et al., 2006; Döring & Kempe, 2008; Meyer et al., 2008; Wooles et al., 2010; Huang et al., 2013). The bonding between the rare-earth metal and benzyl ligands depends both on the size of metal and the number of coordinated THF ligands. In the series of tris-THF derivatives [RE(CH2Ph)3(THF)3], in line with the lanthanide contraction, the bonding changes from three η2-bonded benzyl ligands for the large early, to a mix of η1-/η2-benzyls for the mid- and three η1-benzyls for the smaller, late metals (Wooles et al., 2010). Metal size also matters for bis-THF compounds, [RE(CH2Ph)3(THF)2]; the small scandium atom can only support three η1-bound benzyls (Meyer et al., 2008) whereas [Er(CH2Ph)3(THF)2] features one η2- and two η1-coordinated benzyl ligands (Huang et al., 2013). Here we report the solid-state X-ray structure of [Lu(CH2Ph)3(THF)2].
2. Structural commentary
The molecular structure of [Lu(CH2Ph)3(THF)2] (1) (Fig. 1) reveals that the Lu center is coordinated by two oxygen atoms of the THF ligands and three methylene carbon atoms of the benzyl groups. The disposition of the two THF ligands about the lutetium center is almost linear [O1—Lu—O2 = 177.10 (6)°], thus suggesting a trigonal–bipyramidal structure with the two THF ligands occupying the axial sites and the benzyl groups in the equatorial positions, consistent with the observed solution behavior (Meyer et al., 2008). The Lu—C distances are essentially equal [Lu—C10 = 2.401 (3), Lu—C20 = 2.380 (3), Lu—C30 = 2.404 (3) Å] and the equatorial C—Lu—C angles are close to the expected value of 120° [C10—Lu—C20 = 121.59 (10), C10—Lu—C30 = 123.98 (9), C20—Lu—C30 = 114.38 (10)°], albeit with some deviation from the ideal value. This deviation can be attributed to the presence of an additional interaction from the ipso carbon atom of one of the benzyl ligands, as reflected in the Lu—Cipso distances and Lu—C—Cipso angles: Lu—C11 = 2.920 (3) vs 3.317 (2) and 3.267 (3) Å, for Lu—C21 and Lu—C31, respectively, and Lu—C10—C11 = 94.94 (16) vs Lu—C20—C21 116.79 (17) and Lu—C30—C31 112.80 (17)°. At the same time, the bond distance between the benzylic and ipso carbon atoms for the η2-bonded benzyl group [C10—C11 = 1.467 (4) Å] is not significantly different from those of the η1-bonded benzyls [C20—C21 = 1.475 (3), C30—C31 = 1.470 (4) Å].
The mixed modes of benzyl coordination in the title compound are in contrast to the structure of the related hexacoordinate tris-THF compound, [Lu(CH2Ph)3(THF)3], in which all of the benzyl ligands are η1-coordinated (Meyer et al., 2008, 2013). The structural results provide yet another example of the importance of the metal size in the series of homologous [RE(CH2Ph)3(THF)2] (RE = Sc, Er, Lu) compounds: the complex featuring the small scandium center shows all three benzyl ligands adopting the η1-bonding mode (Meyer et al., 2008), whereas the larger lutetium can allow one of the three benzyl ligands to adopt the more sterically-demanding η2-bonding mode; indeed, the Lu compound is isomorphous with the similarly-sized erbium complex, [Er(η2-CH2Ph)(η1-CH2Ph)2(THF)2] (Huang et al., 2013), with metrical parameters reflecting the small decrease in ionic radius from erbium to lutetium (Shannon, 1976).
3. Supramolecular features
The closest intermolecular contacts are between benzyl carbons C11 and C12 and the THF methylene-group hydrogen H1B (at x − 1, y, z), at 2.80 and 2.89 Å, respectively, and between the benzyl carbon C16 and the phenyl-group hydrogen H22 (at −x, −y, 1 − z), at 2.86 Å. These interactions connect the complexes in a supramolecular ribbon running along the a-axis direction
4. Database survey
For related lanthanide complexes of the form [M(CH2Ph)3(THF)2], only the structure of the Er analogue has been reported (Huang et al., 2013); the structure of the related Sc complex has also been described (Meyer et al., 2008). The structures of the [M(CH2Ph)3(THF)3] complexes have been more exhaustively determined, with the lanthanides La (Bambirra et al., 2006), Ce (Wooles et al., 2010), Pr (Wooles et al., 2010), Nd (Döring & Kempe, 2008; Wooles et al., 2010), Sm (Wooles et al., 2010), Gd (Wooles et al., 2010; Huang et al., 2013), Dy (Wooles et al., 2010), Ho (Huang et al., 2013), Er (Wooles et al., 2010; Huang et al., 2013), and Lu (Meyer et al., 2008) being reported, the related Sc (Meyer et al., 2008) and Y (Hardera et al., 2008; Mills et al. 2009) analogues are also known.
5. Synthesis and crystallization
The synthesis, solution structure and spectroscopic characterization of [Lu(CH2Ph)3(THF)2] (1) have been reported previously (Meyer et al., 2008). The preparation and characterization of the related compounds [Sc(CH2Ph)3(THF)2] and [RE(CH2Ph)3(THF)2] (RE = Sc, Lu) were also reported at that time.
X-ray quality crystals of compound 1 were obtained by cooling a dilute toluene solution of the compound to 243 K for several days.
6. Refinement
Crystal data, data collection and structure . Hydrogen atoms were generated in idealized positions according to the sp2 or sp3 geometries of their attached carbon atoms, and given isotropic displacement parameters Uiso(H) = 1.2Ueq(parent atom). C—H distances in the CH2 groups were constrained to 0.99 Å and those in phenyl-ring C–H groups to 0.95 Å.

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