The dihedral angle between adjacent isoxazole and benzene rings is 84.0 (2)°. The compound displays intra- and inter-molecular ?-? stacking inter-actions between the isoxazole rings, the shortest centroid-centroid distances being 3.837?(3) and 3.634?(3)?Å, respectively. The mol-ecules are stacked in columns along the a axis with short Br?Br contacts [3.508?(1)?Å].

The dihedral angle between the mean planes of the pyran and phenyl rings is 61.9?(1)°. In the crystal, mol-ecules are linked by two pairs of C-H?O hydrogen bonds, forming dimers. These dimers are linked via a third C-H?O hydrogen bond, forming a two-dimensional network parallel to (10-2).

(+)-(1S,5R,10S)-11,11-Dimeth-yl-4-oxa-tricyclo-[8.4.0.0]tetra-deca-ne-3,12-dione.

Project description:The title compound, C(15)H(22)O(3), was prepared via amino-acid-promoted Robinson annulation followed by tandem Pd/C-mediated hydrogenation and oxidative cyclization. This product was instrumental in determining the feasibility of a stereocontrolled hydrogenation in which the directing hydroxyl group is adjacent to the 6-7-ring network and its olefinic component. The asymmetric unit consists of a single mol-ecule with normal geometric parameters. The absolute configuration was assigned based on the known enanti-omeric prescursor. Inter-molecular C-H?O inter-actions link each mol-ecule with four neighboring mol-ecules.

(?(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.

Project description:In the title compound, C(19)H(20)N(2)O(6), the pyrone and pyran rings adopt envelope conformations with the same common C atom as the flap, the dihedral angle between the planes of the remaining ring atoms being 68.27?(4)°.

Moreover, the planar atoms of the pyrone ring and benzene ring of the coumarin unit are also close to coplanar, the dihedral angle between their mean planes being 8.03?(9)°. The meth-oxy group lies in the plane of the benzene ring, with a dihedral angle between their mean planes of 9.4?(2)°. In the crystal, the molecules are linked by C-H?O hydrogen bonds resulting in sheets of mol-ecules in the ac plane.

The bridging subunits, together with the short bridging strand (NCCOCCN) from each monocycle, define a 24-membered ring (N(4)O(4) donor atom set) that forms a central cavity.

Diammonium tetra-kis-(iso-thio-cyanato)-zincate-1,4,10,13,16-hexa-oxa-cyclo-octa-deca-ne-water (1/2/1).

Project description:The title compound, (NH4)2[Zn(NCS)4]·2C12H24O6·H2O, the result of the reaction of ammonium thio-cyanate, 18-crown-6 and zinc(II) chloride in aqueous solution, exhibits an unusual supra-molecular structure. The Zn atom, two of the thio-cyanate chains and a water mol-ecule, disordered over two positions, lie on a mirror plane. The macrocycle adopts a conformation with approximate D 3d symmetry. The ammonium mol-ecules are contained within the bowl of the macrocycle via extensive N-H?O hydrogen bonds and the complex mol-ecules are linked via N-H?S hydrogen bonds, forming chains along the c-axis direction. The macrocycle is disordered over two positions [refined occupancy ratio = 0.666?(8):0.334?(8)]. The S atoms of two iso-thio-cyanate ligands are disordered within and about the mirror plane.

Project description:In the title compound, C(30)H(27)N(3)O(6), the furan and pyrrolidine rings adopt envelope conformations (with C and N atoms as the flaps, respectively). The piperidine ring is in a distorted boat conformation. The β-lactam ring is planar [maximum deviation = 0.0044 (16) Å] and forms dihedral angles of 30.61 (9) and 85.51 (9)°, respectively, with the attached meth-oxy-phenyl and phen-oxy rings. The crystal packing is stabilized by N-H⋯O and C-H⋯O inter-actions forming R(2) (2)(8), R(2) (2)(20) and R(2) (2)(14) ring motifs. The crystal structure is further consolidated by weak C-H⋯π inter-actions.

Project description:The macrobicyclic title compound, C(24)H(28)N(2)O(7), has two tertiary diamide bridgehead atoms and is composed of a 12-membered ring (N(2)O(2) donor set) and two 18-membered rings (N(2)O(4) donor sets). The solid-state structure shows that each of the amide groups is not coplanar with the adjacent benzene ring and NMR studies indicate that this conformational relationship persists in solution.
