5,7,8,10,11,13,14,16-Octa-hydro-6,15-(ethanoxyethanoxyethano)-1,4:17,20-dietheno[9,12,6,15]benzodioxadiaza-cyclo-docosine.

ABSTRACT: The title compound, C(32)H(40)N(2)O(4), is a 1,10-diaza-18-crown-6 cryptand with an o-terphenyl bridge. In the polyether ring, two adjacent -CH(2)- groups are disordered with very nearly equal populations of two conformers. The ordered bond lengths are normal, with average C-C = 1.511?(3)?Å, C-O = 1.421?(3)?Å, and C-N = 1.466?(4)?Å. The r.m.s. deviations of the three rings of the terphenyl bridge vary from 0.007 to 0.009?Å and the two rings ortho to one another are twisted by 50.75?(5) and 47.76?(4)° with respect to the third ring. The N?N distance is 5.408?(1)?Å.

The title compound, C(32)H(40)N(2)O(4), is a 1,10-diaza-18-crown-6 cryptand with an o-terphenyl bridge. In the polyether ring, two adjacent -CH(2)- groups are disordered with very nearly equal populations of two conformers. The ordered bond lengths are normal, with average C-C = 1.511 (3) Å, C-O = 1.421 (3) Å, and C-N = 1.466 (4) Å. The r.m.s. deviations of the three rings of the terphenyl bridge vary from 0.007 to 0.009 Å and the two rings ortho to one another are twisted by 50.75 (5) and 47.76 ...[more]

Project description:In the crystal structure of the title compound, C(12)H(18)S(5), no significant inter-molecular ?-? inter-actions are found. Weak inter-molecular C-S?? [S?centroid = 3.787?(1)?Å] inter-actions and van der Waals forces may be effective in the stabilization of the structure.

[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).

Project description:In the title mol-ecule, C(11)H(16)O(2)S(5), the two S atoms from the macrocycle are situated on opposite sides of the mean plane of the five-membered ring, deviating from it by 1.288?(3) and 1.728?(3)?Å. In the crystal, weak inter-molecular C-H?S and C-H?O hydrogen bonds link the mol-ecules into layers parallel to (100). The crystal studied was a racemic twin.

Crystal structure of 1-benzyl-4-(4-chloro-phen-yl)-2-imino-1,2,5,6,7,8,9,10-octa-hydro-cyclo-octa-[b]pyridine-3-carbo-nitrile.

Project description:The title compound, C25H24ClN3, comprises a 2-imino-pyridine ring fused with a cyclo-octane ring, which adopts a twist boat-chair conformation. In the crystal, C-H?N inter-actions form R 2 (2)(14) ring motifs and mol-ecules are further connected by weak C-H?? inter-actions. The resulting supra-molecular structure is a two-dimensional framework parallel to the ab plane.

(?(4)-Cyclo-octa-tetra-ene)(?(8)-cyclo-octa-tetra-ene)iodido-tantalum(V).

Project description:The title complex, [Ta(?(4)-C8H8)(?(8)-C8H8)I], lies across a crystallographic mirror plane that includes the Ta(V) atom and the iodide ligand. One cyclo-octa-tetra-ene (cot) ring is ?(4)-coordinating and is bis-ected by the mirror plane. The fold angle between the plane of the coordinating butadiene portion and the middle plane of the ring is 27.4?(4)°. An additional minor fold angle of 9.3?(7)° exists between the final plane in the ring and the middle plane. The other cot?ring is ?(8)-coordinating and is also cut by the mirror plane. In this case, the ring is disordered over the mirror plane, and one position is modeled with appropriate restraints and constraints with respect to distances, angles and displacement parameters (the second position is generated by symmetry). This ring is nearly planar, with an r.m.s. deviation of only 0.05?Å when all eight C atoms are included in the calculation. Pairs of inter-molecular ?(8)-cot?rings are parallel stacked and slightly off center, with a centroid-centroid distance of 3.652?Å. No other significant inter-molecular inter-actions are observed. The compound is of inter-est as the first structurally characterized mixed halogen-cot?complex of the group 5 metals and contains the longest terminal Ta-I distance [3.0107?(5)?Å] reported to date.

2,3,10,11-Tetra-meth-oxy-6,7,14,15-tetra-hydro-6,14-methano-cyclo-octa-[1,2-b;5,6-b']diquinoline.

Project description:The racemic title compound, C(27)H(26)N(2)O(4), crystallizes with its central carbon bridge on a twofold axis. It forms parallel chains of mol-ecules utilizing aryl offset face-face inter-actions with an interplanar distance of about 3.5?Å. These chains associate further by means of pairs of O-CH(2)-H?? (with H-ring distances ranging from 2.69 to 2.95?Å) and O-CH(2)-H?N motifs. The meth-oxy groups in this structure are coplanar with the aromatic rings to which they are attached. This is recognized as being common behaviour amongst aromatic meth-oxy compounds.

Project description:The asymmetric unit of the title compound, [K(C12H24O6)(C4H8O)2][Co(C14H10)2]·C4H8O, consists of one cationic potassium complex, one anionic cobalt dianthracene complex and one tetra-hydro-furan solvent mol-ecule. The potassium cation is situated at the centre of an 18-crown-6 mol-ecule and between two tetra-hydro-furan mol-ecules, the latter coordin-ating above and below the mean plane formed by the O atoms of the crown ether mol-ecule. The Co atom is coordinated by eight C atoms of two anthracene mol-ecules in an ?(4) manner. The third free tetra-hydro-furan mol-ecule shows orientational disorder on two partially occupied positions [occupancy ratio 0.561?(8):0.439?(8)].

Project description:The previously reported room-temperature crystal structure [Jaud Baldy, Negrel, Poite & Chanon (1993 ▶). Z. Kristallogr.204, 289-291] of the title compound, C(20)H(8)Cl(12), is monoclinic with Z' = 1, whereas the 90 K structure reported herein is triclinic with Z' = 2 and shows a 2% volume contraction. The crystallographically independent unit chosen consists of both enanti-omers (Λ and Δ) of this propeller-like mol-ecule. Both enanti-omers display quasi-twofold symmetry, with average bond-length/bond-angle deviations of 0.0018 (4) Å and 0.41 (2)° for Λ, and 0.0026 (4) Å and 0.50 (2)° for Δ.
