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

ABSTRACT: 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).

Tris[μ-2,2'-(azinodimethylidyne)diphenolato-κO,N:N',O']diiron(III) tetra-hydro-furan tetra-solvate.

Project description:In the title binuclear iron(III) complex, [Fe(2)(C(14)H(10)N(2)O(2))(3)]·4C(4)H(8)O or [Fe(2)(salda)(3)]·4THF [H(2)salda = 2,2'-(azinidimethyl-ene)diphenolate and THF is tetra-hydro-furan], the ligand possesses a rotationally flexible single N-N bond. Three dinucleating O,N:N',O'-donor ligands provide three diazine (=N-N=) bridges between the metal ions, yielding a binuclear triple helicate structure with crystallographic C(2) symmetry, the rotation axis bis-ecting one N-N bond.

Project description:In the tetra-hydro-furan solvate of the title salt, C12H36N6P3 (+)·C24H20B(-)·C4H8O, the cation features short P-P bond lengths [2.1111?(11) and 2.1364?(10)?Å] and a distinctly bent P-P-P angle [104.67?(4)°] that confirm that the mol-ecule is not allene-like. In the crystal, the solvent mol-ecule is linked to the cation via a weak C-H?O hydrogen bond.

Project description:The title compound, C21H15O4P·0.5C4H8O, contains an ordered phosphane oxide in a general position and a tetra-hydro-furan solvent mol-ecule disordered about a twofold axis. All three aldehyde substituents are nearly coplanar with their attached benzene rings, with C-C-C-O torsion angles in the range 1.64 (17)-4.24 (19)°. All three have different conformations with respect to the P=O group, one syn, one anti, and one gauche. Two of the aldehyde substituents form inter-molecular C-H⋯O contacts.

1,3-Benzothia-zolium tetra-chlorido-aurate(III) tetra-hydro-furan solvate.

Project description:In the crystal structure of the title ionic compound (C(7)H(6)NS)[AuCl(4)]·C(4)H(8)O, the [AuCl(4)](-) anion shows a typical square-planar geometry. Numerous weak C-H?Cl hydrogen bonds between [AuCl(4)](-) and the 1,3-benzothia-zolium units form layers comprised of 24-membered rings in which hydrogen-bonded tetra-hydro-furan (THF) solvent mol-ecules are accommodated. C-H?Cl inter-actions between THF and [AuCl(4)](-) from adjacent layers result in bilayers. These are further stabilized by ?-? inter-actions between the thia-zole and benzene rings [centroid-centroid distance = 3.971?(3)?Å], resulting in the formation of a three-dimensional supra-molecular assembly.

Project description:In the centrosymmetric binuclear complex of the title solvate, [Sm(2)(C(21)H(15)N(2)O(3))(2)(C(4)H(8)O)(2)]·2C(4)H(8)O, the Sm(III) is coordin-ated in a distorted monocapped octa-hedral geometry by four O atoms and two N atoms from two tridentate deprotonated 2-{bis-[(2-oxidobenzyl-idene)amino]-meth-yl}phenolate ligands and an O atom of a tetra-hydro-furan (THF) mol-ecule. The Sm?Sm distance in the complex is 3.8057?(4)?Å. Parts of the coordinating THF mol-ecule are disordered over two sets of sites in a 0.56?(3):0.44?(3) ratio. The complex and solvent mol-ecules are linked into a three-dimensional structure via C-H?O hydrogen-bonding inter-actions.

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.
