In the title compound, C22H23NO2S, the inner pyrrolidine ring (A) adopts an envelope conformation with the methine C atom opposite the fused C-N bond as the flap. The thio-pyran ring (C) has a half-chair conformation and its mean plane is inclined to the fused benzene ring by 1.74 (11)°, and by 60.52 (11)° to the mean plane of pyrrolidine ring A. In the outer pyrrolidine ring (B), the C atom op...

Injury to spinal cord was produced in rats by the clip compression technique by placing the aneurysm clip extradurally for 30 seconds. The traumatised spinal segment and the adjoining upper segment were used for biochemical estimations. Motor function of the injured rats was evaluated using the inclined plane. Phospholipid phosphorus values were significantly decreased in the injured spinal seg...

In the title compound, C19H18FNO3S, the five-membered oxazolidine ring adopts an envelope conformation with the methine C atom of the fused bond as the flap. Its mean plane is oriented at a dihedral angle of 50.38 (1)° with respect to the fluoro-phenyl ring. The six-membered thio-pyran ring has a half-chair conformation and its mean plane is almost coplanar with the fused benzene ring, making a...

In the title compound, C23H23NO8, the dihedral angle between the five- and six-membered rings of the indene-dione moiety is 3.09 (13)°. The mean plane of the five-membered ring (which has a flat envelope conformation with the spiro C atom as the flap) is inclined to the mean plane of the central five-membered ring of the pyrrolizine unit by 76.48 (12)°. This central ring has a twist conformatio...

Anterior crossbite correction in early mixed dentition is highly recommended as this kind of malocclusion do not diminish with age. Uncorrected anterior crossbite may lead to abnormal wear of the lower incisors, dental compensation of mandibular incisors leading to thinning of labial alveolar plate and/or gingival recession. There are several methods for solving this problem. In this article we...

In the title compound, C15H14N4O2, the triazolo-pyrimidine ring system is almost planar (r.m.s. deviation = 0.02 Å) and the phenyl ring is inclined to its mean plane by 42.45 (9)°. The carboxyl group is inclined to the triazolo-pyrimidine ring mean plane by 57.8 (3)°. In the mol-ecule, there is a short C-H⋯O contact involving the carbonyl O atom and an H atom of the adjacent methyl substituent....

On an inclined glass plate the slug Agriolimax orients and creeps upward or downward. The angle of orientation on the plane (theta) is proportional to the logarithm of the component of gravity in the creeping plane. The coefficient of variability of the measured values of (theta) decreases linearly as the logarithm at the gravity component in the creeping plane increases. The cosine of the angl...

In the title compound, C13H19NO3, the dioxane ring adopts a chair conformation. Its mean plane is inclined to the 4-meth-oxy-phenyl ring by 70.34 (9)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(16) ring motif. The dimers are linked via C-H⋯π inter-actions, forming two-dimensional networks lying parallel to the ac plane.

The mol-ecule of the title compound, C9H9N3O2S, is built up from fused five- and six-membered rings connected to methyl-sulfanyl and nitro groups, respectively. The mean plane through the fused ring system is inclined slightly relative to the plane passing through the nitro group [dihedral angle = 3.6 (2)°]. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and π-π inter-actions bet...
