Crystal structure of tri-benzyl-bis-(tetra-hydro-furan-?O)lutetium(III).

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

Crystal structure of tetra-kis-(tetra-hydro-furan-κO)bis-(tri-fluoro-methane-sulfonato-κO)iron(II).

Project description:The title compound, [Fe(CF3SO3)2(C4H8O)4], is octa-hedral with two tri-fluoro-methane-sulfonate ligands in trans positions and four tetra-hydro-furane mol-ecules in the equatorial plane. By the conformation of the ligands the complex is chiral in the crystal packing. The compound crystallizes in the Sohncke space group P212121 and is enanti-omerically pure. The packing of the mol-ecules is determined by weak C-H⋯O hydrogen bonds. The crystal studied was refined as a two-component inversion twin.

Crystal structure of bis-(acetyl-acetonato-?(2) O,O')(tetra-hydro-furan-?O)(tri-fluoro-methane-sulfonato-?O)iron(III).

Project description:The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetyl-acetonate; OTf = tri-fluoro-methane-sulfon-ate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe(3+) atom in a slightly distorted octa-hedral environment [Fe-O bond-length range = 1.9517?(11)-2.0781?(11)?Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622?(16):0.378?(16). Weak inter-molecular C-H?O and C-H?F hydrogen-bonding inter-actions generate a two-dimensional supra-molecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis-(acetyl-acetonato)iron(III) complex.

Crystal structure of di-μ-tri-hydro-(penta-fluoro-phenyl)-borato-tetra-kis-(tetra-hydro-furan)-disodium.

Project description:The title compound, [Na(μ-C6F5BH3)(C4H8O)2]2, represents a dimeric structure of sodium and organoborohydride, located about a centre of inversion. The Na⋯B distances of 2.7845 (19) and 2.7494 (18) Å were apparently longer than the Li⋯B distances (2.403-2.537 Å) of the lithium organotri-hydro-borates in the previous reports. Moreover, an inter-action between the sodium atom and one fluorine atom on the 2-position of the benzene ring is observed [Na-F = 2.6373 (12) Å]. In the crystal, the dimeric mol-ecules are stacked along the b-axis via a π-π inter-action between the benzene rings.

Project description:The title pseudo-polymorph of 3-(tri-phenyl-phospho-ranyl-idene)-2,5-di-hydro-furan-2,5-dione crystallizes with a tetra-hydro-furan solvent mol-ecule, viz. C22H17O3P·C4H8O. The succinic anhydride ring is approximately planar (r.m.s. deviation = 0.032?Å). The tetra-hydro-furan mol-ecule is disordered over two orientations about a pseudo-twofold axis with refined occupancy ratio 0.718?(4):0.282?(4). In the crystal, C-H?O hydrogen bonds link mol-ecules of the di-hydro-furan-2,5-dione derivative into chains parallel to the b axis and arranged into layers stacked along [100] alternating with hydrogen-bonded tetra-hydro-furan layers.

Crystal structure of tris-(phenyl-seleno-lato-?Se)tris-(tetra-hydro-furan-?O)thulium(III).

Project description:In the title compound, [Tm(C6H5Se)3(C4H8O)3], the Tm(III) atom lies on a threefold rotation axis and is coordinated by three phenyl-seleno-late ligands and three tetra-hydro-furan ligands leading to a distorted fac-octa-hedral coordination environment. The Tm-Se and Tm-O bond lengths are 2.7692?(17) and 2.345?(10)?Å, respectively, and the bond angles are 91.32?(6)° for Se-Tm-Se, 92.6?(2) and 94.4?(2)° for Se-Tm-O, and 81.2?(3)° for O-Tm-O. In the crystal, the discrete complexes are linked by van der Waals inter-actions only. The crystal was refined as a non-merohedral twin (ratio = 0.65:0.35).

[N,N'-Bis(2,6-diisopropyl-phen-yl)methanimidamidato][?-1,4-bis-(tri-methyl-sil-yl)cyclo-octa-tetra-enyl](tetra-hydro-furan)-samarium(III) toluene monosolvate.

Project description:The title compound, [Sm(C(25)H(35)N(2))(C(14)H(24)Si(2))(C(4)H(8)O)]·C(7)H(8), 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-diisopropyl-phen-yl)methanimidamide] and Li(2)(COT'') [COT'' = 1,4-bis-(trimethyl-sil-yl)cyclo-octa-tetra-enyl] in tetra-hydro-furan (THF). Despite the presence of two very bulky ligands (COT'' and DippForm), the mol-ecule still contains one coordinated THF ligand. The overall coordination geometry around the Sm(III) atom resembles a three-legged piano-stool with the COT'' ligand being ?(8)-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 mol-ecule of toluene, the refined ratio of the two components being 0.80?(4):0.20?(4).

Epalrestat tetra-hydro-furan monosolvate: crystal structure and phase transition.

Project description:The title compound, epalrestat {systematic name: (5Z)-5-[(2E)-2-methyl-3-phenyl-prop-2-en-1-yl-idene]-4-oxo-2-sulfanyl-idene-1,3-thia-zolidine-3-acetic acid}, crystallized as a tetra-hydro-furan monosolvate, C15H13NO3S2·C4H8O. Epalrestat, an important drug for diabetic neuropathy, has been reported to exist in polymphic, solvated and co-crystal forms. In the mol-ecule reported here, the phenyl ring is inclined to the rhodamine ring by 22.31?(9)°, and the acetic acid group is almost normal to the rhodamine ring, making a dihedral angle of 88.66?(11)°. In the crystal, pairs of O-H?O hydrogen bonds are observed between the carb-oxy-lic acid groups of epalerstat mol-ecules, forming inversion dimers with an R22(8) loop. The dimers are linked by pairs of C-H?O hydrogen bonds, forming chains along [101]. The solvate mol-ecules are linked to the chain by a C-H?O(tetra-hydro-furan) hydrogen bond. A combination of thermal analysis and powder X-ray diffraction revealed that title compound desolvated into epalerstat Form II. One C atom of the tetra-hydro-furan solvate mol-ecule is positionally disordered and has a refined occupancy ratio of 0.527?(18):0.473?(18).
