The title compound, (C21H33N2O)2[SmCl5(C4H8O)]·C7H8·C4H8O, has a layered structure in which each distorted octahedral [SmCl5(THF)]2− unit (THF is tetrahydrofuran) is capped by two cations. The central metal SmIII atom of the [SmCl5(THF)]2− anionic unit is coordinated by five Cl atoms and one THF O atom, forming a distorted octahedral geometry. The displays C—H⋯Cl and O—H⋯Cl hydrogen bonding. The structure exhibits disorder of the solvent.

All manipulations were performed under pure argon with rigorous exclusion of air and moisture by using standard Schlenk techniques.THF was degassed and distilled from sodium benzophenone ketyl under argon prior to use. N-aryloxo imidazolium chloride [HO-3,5-di-tBu—C6H2-2-CH2{CH(iPrNCHCHN)}]Cl was prepared according to the literature (Li et al.,2005). A suspension of N-aryloxoimidazolium chloride [HO-3,5-di-tBu—C6H2-2-CH2{CH(iPrNCHCHN)}]Cl (1.46 g, 4 mol) in THF was added to a suspension of SmCl3 (0.52 g, 2 mol) in THF at room temperature. A clean solution was obtained after 10 min under stirring. After concentration and centrifugion, the resulting solution was kept at room temperature in order to obtain colorless crystals (2.05 g, 84% yield). Anal.Calcd.

H atoms were positioned geometrically (C—H = 0.95–1.00 A\%) and included in the
in the riding-model approximation, with Uiso(H) = 1.2 or 1.5 times Ueq(C). The highest electron-density peak is 0.97 A \% from atom H24. The program SQUEEZE was used to handle the disordered THF and toluene molecules.Recently, the anionic functionalized N-heterocyclic carbenes( NHCs), such as amino- or phenoxo(alkoxo)-NHCs, have attracted much more attention particularly in the field of rare earth metals as the anionic tether can be used as anchor to enhance the bond of NHC to these electropositive metals (Arnold et al.,2006; Liddle et al., 2007). A series of anionic functionalized NHCs have been synthesized and structurally characterized (Arnold et al., 2009; Wang et al., 2006a ). However, the reaction of ligands with cerium triiodide (Arnold et al.,2005) or ytterbium trichloride (Wang et al., 2006a) in the presence of organic base gives no desired product. Especially noteworthy is the cleavage reaction of the ligand that occurs during the reaction process ( Wang et al., 2006b ). For a better understanding of the reason, the complex [NdCl5(THF)]2-[HO-3,5-di-tBu—C6H2-2-CH2{CH(NCHCHNiPr)]2+ (Yao et al., 2007) has been studied. In order to further study these compounds, the title complex has been synthesized. Although the ion-pair structure has recently been reported for LnI3 in sulfonium-based ionic liquids (Babai et al.,2005), its structural feature is different from that of the title complex. In [SEt3]3[NdI6], SEt3 is a triethylsulfonium cation; an octahedron [NdI6]3- is capped by triethylsulfonium cations (SEt3) via the coordination of Nd3+to SEt3. The X-ray crystal analysis of the title complex indicates that the bis-[(3,5-ditertbutyl-2-hydroxybenzyl)N-isopropylimidazolyl] samarium pentachloride consists of an anion [SmCl5(THF)]2-and two cations [HO-3,5-di-tBu—C6H2-2-CH2{CH(iPrNCHCHN)}]2+. The central metal Sm in the anionic unit [SmCl5(THF)]2- coordinates to five Cl atoms and one oxygen atom from a solvent THF molecule to form a six-coordinated distorted octahedron geometry, which is similar to the reported complex (Yao et al., 2007). The four chlorines Cl(1), Cl(2), Cl(3) and Cl(4) can be considered to occupy the equatorial positions within the octahedron about the lanthanide center. The O(3) and Cl(5) occupy the two axial sites. The angle O(3)—Sm—Cl(5) is slightly distorted from the ideal value of 180° to 174.99 (8)°. The Sm—Cl average bond lengths of 2.6743Å in the title complex are somewhat shorter than 2.789 (2)Å and 2.827Å found in the complex [(SiMe3)2NC(NC6H11)2]Sm(µ-Cl)2Li(THF)2 (Yao et al., 2004). The Sm—O(3) bond of 2.452 (3)Å is comparable to 2.448 Å found in the complex [CH3C5H4]2Sm[SC(SPh)NPh](THF)]2 (Lu et al., 2001). Especially noteworthy is the difference in the network of intermolecular and intramolecular hydrogen bonds. In the complex reported by Yao et al. (2007) the hydrogen bonds only exist between the O—H of phenol and Cl. However, in the title complex the hydrogen bonds not only exist in between the O—H of phenol and Cl, but also occur between C—H of imidazole ring, benzyl and isopropyl from the imidazolium ring.

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. |
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. |

Recently, the anionic functionalized N-heterocyclic carbenes( NHCs), such as amino- or phenoxo(alkoxo)-NHCs, have attracted much more attention particularly in the field of rare earth metals as the anionic tether can be used as anchor to enhance the bond of NHC to these electropositive metals (Arnold et al.,2006; Liddle et al., 2007). A series of anionic functionalized NHCs have been synthesized and structurally characterized (Arnold et al., 2009; Wang et al., 2006a ). However, the reaction of ligands with cerium triiodide (Arnold et al.,2005) or ytterbium trichloride (Wang et al., 2006a) in the presence of organic base gives no desired product. Especially noteworthy is the cleavage reaction of the ligand that occurs during the reaction process ( Wang et al., 2006b ). For a better understanding of the reason, the complex [NdCl5(THF)]2-[HO-3,5-di-tBu—C6H2-2-CH2{CH(NCHCHNiPr)]2+ (Yao et al., 2007) has been studied. In order to further study these compounds, the title complex has been synthesized. Although the ion-pair structure has recently been reported for LnI3 in sulfonium-based ionic liquids (Babai et al.,2005), its structural feature is different from that of the title complex. In [SEt3]3[NdI6], SEt3 is a triethylsulfonium cation; an octahedron [NdI6]3- is capped by triethylsulfonium cations (SEt3) via the coordination of Nd3+to SEt3. The X-ray crystal analysis of the title complex indicates that the bis-[(3,5-ditertbutyl-2-hydroxybenzyl)N-isopropylimidazolyl] samarium pentachloride consists of an anion [SmCl5(THF)]2-and two cations [HO-3,5-di-tBu—C6H2-2-CH2{CH(iPrNCHCHN)}]2+. The central metal Sm in the anionic unit [SmCl5(THF)]2- coordinates to five Cl atoms and one oxygen atom from a solvent THF molecule to form a six-coordinated distorted octahedron geometry, which is similar to the reported complex (Yao et al., 2007). The four chlorines Cl(1), Cl(2), Cl(3) and Cl(4) can be considered to occupy the equatorial positions within the octahedron about the lanthanide center. The O(3) and Cl(5) occupy the two axial sites. The angle O(3)—Sm—Cl(5) is slightly distorted from the ideal value of 180° to 174.99 (8)°. The Sm—Cl average bond lengths of 2.6743Å in the title complex are somewhat shorter than 2.789 (2)Å and 2.827Å found in the complex [(SiMe3)2NC(NC6H11)2]Sm(µ-Cl)2Li(THF)2 (Yao et al., 2004). The Sm—O(3) bond of 2.452 (3)Å is comparable to 2.448 Å found in the complex [CH3C5H4]2Sm[SC(SPh)NPh](THF)]2 (Lu et al., 2001). Especially noteworthy is the difference in the network of intermolecular and intramolecular hydrogen bonds. In the complex reported by Yao et al. (2007) the hydrogen bonds only exist between the O—H of phenol and Cl. However, in the title complex the hydrogen bonds not only exist in between the O—H of phenol and Cl, but also occur between C—H of imidazole ring, benzyl and isopropyl from the imidazolium ring.
