Methyl 2-(1a,4a-dimethyl-2,8-dioxo-2,3,4,4a,5,6,7,8-octa-hydro-1aH-1-oxacyclo-propa[d]naphthalen-7-yl)acrylate.

ABSTRACT: The title compound, C(16)H(20)O(5), was synthesized from ilicic acid [2-(8-hy-droxy-4a,8-dimethyl-deca-hydro-naphthalen-2-yl)acrylic acid], which was isolated from the chloro-form extract of the aerial part of Inula viscose (L) Aiton [or Dittrichia viscosa- (L) Greuter]. The molecule is built up from two fused six-membered rings, the epoxidized six-membered ring adopts a half-chair conformation while the other ring displays a perfect chair conformation. The crystal structure features C-H?O hydrogen bonds.

Methyl 2-(4a,8-Dimethyl-7-oxodeca-hydro-naphthalen-2-yl)acrylate.

Project description:The title compound, C(16)H(24)O(3), was isolated from the aerial part of Inula Viscosa- (L) Aiton [or Dittrichia Viscosa- (L) Greuter]. The mol-ecule contains two fused (trans) six-membered rings which both exibit a chair conformation. In the crystal, mol-ecules are linked into chains along [100] by weak C-H?O hydrogen bonds involving the methyl and carbonyl groups.

4a-Hy-droxy-3,3,6,6-tetra-methyl-9-[6-(3,3,6,6-tetra-methyl-1,8-dioxo-2,3,4,5,6,7,8,9-octa-hydro-1H-xanthen-9-yl)pyridin-2-yl]-2,3,4,4a,5,6,7,8,9,9a-deca-hydro-1H-xanthene-1,8-dione ethanol hemisolvate hemihydrate.

Project description:The pyridine ring in the title compound, C(39)H(47)NO(7)·0.5C(2)H(5)OH·0.5 H(2)O, is connected to one 3,3,6,6-tetra-methyl-1,8-dioxoxanthenyl and one 4a-hy-droxy-3,3,6,6-tetra-methyl-1,8-dioxodeca-hydroxanthenyl substituent in the 2- and 6-positions of the ring. In the former substituent, the six-membered xanthenyl ring adopts a flattened envelope conformation (with the methine C atom as the flap) while in the latter, the six-membered xanthenyl ring adopts a twisted envelope conformation (with the C atom bearing the hy-droxy group representing the flap). The hy-droxy H atom forms an intra-molecular hydrogen bond to the pyridyl N atom. An ethanol solvent mol-ecule is disordered with respect to a water mol-ecule in a 1:1 ratio. The water mol-ecule itself is disordered over two positions of equal occupancy.

4a-Methyl-2,3,4,4a-tetra-hydro-1H-carbazole-6-sulfonamide.

Project description:In the title mol-ecule, C(13)H(16)N(2)O(2)S, the nine non-H atoms comprising the indole residue are approximately coplanar (r.m.s. deviation = 0.031?Å). The partially saturated ring adopts a chair conformation. One amine H forms an inter-molecular N-H?O hydrogen bond to a sulfonamide O atom, while the other amine H form is connected to the indole N atom of an adjacent mol-ecule via an N-H?N hydrogen bond, resulting in a three-dimensional architecture.

Tris[(1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne)rubidium] heptaantimonide-ammonia (1/4).

Project description:The crystal structure of the title compound, [Rb(C(12)H(24)O(6))](3)[Sb(7)]·4NH(3), fills the gap between the already known Zintl anion ammoniates {[Cs(18-crown-6)](3)Sb(7)}(2)·9NH(3) [Wiesler (2007 ▶). Dissertation, Universität Regensburg, Germany] and [K(18-crown-6)](3)Sb(7)·4NH(3) [Hanauer (2007 ▶). Dissertation, Universität Regensburg, Germany]. As in the two known compounds, the anti-mony cage anion in this crystal structure is coordinated by three alkali cations. The coordination spheres of each of the cations are saturated by 18-crown-6 mol-ecules. The ammonia mol-ecules of crystallization are situated between the crown ethers. The neutral, mol-ecular [Rb(18-crown-6)](3)Sb(7) units are inter-connected by multiple dipole-dipole interactions between ammonia and 18-crown-6.
