The title compound, [Sm(C25H35N2)(C14H24Si2)(C4H8O)]·C7H8, was prepared by treatment of anhydrous samarium trichloride with a 1:1 mixture of in situ-prepared Li(DippForm) [DippFormH = N,N′-bis­(2,6-diisopropyl­phen­yl)methanimidamide] and Li2(COT′′) [COT′′ = 1,4-bis­(trimethyl­sil­yl)cyclo­octa­tetra­enyl] in tetra­hydro­furan (THF). Despite the presence of two very bulky ligands (COT′′ and DippForm), the mol­ecule still contains one coordinated THF ligand. The overall coordination geometry around the SmIII atom resembles a three-legged piano-stool with the COT′′ ligand being η8-coordinated and the DippForm anion acting as an N,N′-chelating ligand [Sm—N = 2.5555 (15) and 2.4699 (15) Å]. The asymmetric unit also contains a disordered mol­ecule of toluene, the refined ratio of the two components being 0.80 (4):0.20 (4).

A hot topic in current organolanthanide chemistry is the search for alternative spectator ligands other than cyclopentadienyls which are able to satisfy the coordination requirements of the large lanthanide cations (Edelmann et al., 2002). Among the most successful approaches in this field is the use of amidinate ligands of the general type [RC(NR')2]- (R = H, alkyl, aryl; R' = alkyl, cycloalkyl, aryl, SiMe3) which can be regarded as steric cyclopentadienyl equivalents (Bailey & Pace, 2001; Edelmann, 2009). Closely related very bulky N,N'-disubstituted formamidinate ligands such as DippForm- [DippFormH = N,N'-bis(2,6-diisopropylphenyl)methanimidamide] have also been frequently employed in this area (Cole et al., 2007; Junk & Cole, 2007]. Another ligand system besides cyclopentadienyl, which is traditionally very important in organolanthanide chemistry, is the cyclooctatetraenyl dianion (= COT) (Edelmann, 1995) and its ring-substituted derivatives such as 1,4-bis(trimethylsilyl)cyclooctatetraenyl (= COT'') (Burton et al., 1989; Burton et al., 1993). Rare-earth metal complexes of the type (COT)Ln[RC(NR')2](THF) have been reported by Schumann et al. (1995). These compounds all comprise the unsubstituted COT ligand and moderately bulky N,N'-bis(trimethylsilyl) benzamidinate ligands (Schumann et al., 1995). We were interested in the question if THF-free compounds of this type would be accessible by combining both the bulky COT'' and the DippForm ligand in the coordination sphere of a lanthanide ion. The first compound of this series, [η8-1,4-bis(trimethylsilyl)cyclooctatetraenyl][N,N'-bis(2,6-diisopropyl­phenyl)formamidinato](tetrahydrofuran)samarium(III) [= (COT'')Sm­(DippForm)(THF), was synthesized by treatment of anhydrous samarium trichloride simultaneously with in situ-prepared Li(DippForm) and Li2(COT'') in THF. Work-up followed by recrystallization from toluene afforded the dark red title compound. Besides X-ray crystallography, the title compound was also characterized by elemental analysis and spectroscopic methods. Dark red, highly air-sensitive, rod-like single crystals of the title compound were obtained by slow cooling of a saturated solution in toluene to 278 K. Surprisingly, despite the presence of two very bulky ligands, COT'' and DippForm, the molecule still contains one coordinated THF ligand. Thus the overall coordination geometry around Sm resembles a three-legged piano-stool with the COT'' ligand being η8-coordinated and the DippForm- anion acting as N,N'-chelating ligand (Sm—N distances: Sm1—N1, 2.5555 (15); Sm1—N2, 2.4699 (15) Å). The N1—C15—N2 angle of the formamidinate unit is 120.10 (15)°.

Preparation of [η8-1,4-bis(trimethylsilyl)cyclooctatetraenyl][N,N'-bis(2,6-diisopropyl­phenyl)formamidinato](tetrahydrofuran)samarium(III): The reaction was carried out under rigorous exclusion of air and moisture. In a 100 ml-Schlenk-flask, a mixture of 1,4-bis(trimethylsilyl)cycloocta-2,5,7-triene (2.00 g, 8.1 mmol) and N,N'-bis(2,6-diisopropylphenyl)methanimidamide (= DippFormH, 2.90 g, 8.1 mmol) were dissolved in THF (25 ml) and a 1.6 N solution of n-butyllithium in n-hexane (15 ml, 24 mmol) was added. Metalation as completed by stirring for 3 h at room temperature. Anhydrous SmCl3 (2.1 g, 8.1 mmol) was added as solid and stirring was continued for 24 h. A white precipitate (LiCl) was removed by filtration, and the clear red.brown flitrate was evaporated to dryness. The residue was extracted with warm (ca 323 K) toluene (2x20 ml), the combined axtracts were filtered again and diluted with n-pentane (30 ml). Cooling to 278 K for 2–3 d afforded 5.27 g (78%) of [η8-1,4-bis(trimethylsilyl)cyclooctatetraenyl][N,N'-bis(2,6-diisopropylphenyl)formamidinato](tetrahydrofuran)samarium(III) as a dark red microcrystalline solid. Dark red, rod-like X-ray quality single-crystals of the mono-toluene solvate were obtained by recrystallization from toluene.

Refinement top

The asymmetric unit contains a disordered molecule of toluene. The refined ratio of the two components is 0.80 (4):0.20 (4). Since the refined ratio of the second component is only 20% it was not possible to find the maxima for the hydrogen atoms of the methyl group. Also the carbon atoms of the second component were refined isotropically. The hydrogen atoms were included using a riding model, with aromatic C—H = 0.95 Å, methine C—H = 1.00 Å, methylene C—H = 0.99 Å [Uiso(H) = 1.2Ueq(C)] and methyl C—H = 0.98 Å [Uiso(H) = 1.5Ueq(C)].

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. The asymmetric unit contains a disordered molecule of toluene. The refined ratio of the two components is 0.80 (4):0.20 (4). Since the refined ratio of the second component is only 20% it was not possible to find the maxima for the hydrogen atoms of the methyl group. Also the carbon atoms of the second component were refined isotropically.
