The title compound, C24H39N3O6, also known as tris[(S)-N-salicylidenevalinol], crystallizes with two mol-ecules in the asymmetric unit.Abstract:
The title compound, C24H39N3O6, also known as tris[(S)-N-salicylidenevalinol], crystallizes with two molecules in the asymmetric unit. These two molecules form a disc-shaped dimeric box and are linked to each other through 11 O—H⋯O hydrogen bonds. These self-assembled dimers are connected by a 12th hydrogen bond to form a one-dimensional hydrogen-bonded network along the b-axis direction.read more

Asymmetric sulfoxidation of prochiral sulfides using aminoalcohol derived chiral C3-symmetric trinuclear vanadium Schiff base complexes
TL;DR: In this paper, a series of trimeric variants of the efficient and well known Bolm's chiral vanadium salen catalysts are reported. These C 3 -symmetric trinuclear chiral Schiff bases were synthesized by condensing a variety of trialdehydes with optically active amino alcohols.

Stabilization of a Strained Heteroradialene by Peripheral Electron Delocalization.
TL;DR: Dimethylamine and 2,4,6-triformylphloroglucinol react to form a product with a highly contorted nonplanar geometry due to favorable electron delocalization, leading to a structure that retains very little of the aromatic characteristics of the starting material.

A semi-empirical method of absorption correction
TL;DR: An extension of Furnas's method is described in this paper, where the variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level.

Completion and refinement of crystal structures with SIR92
TL;DR: In this paper, an automatic procedure for recovering a complete crystal structure after a direct phasing process is described, which consists mainly of a Fourier recycling method that can be implemented in any direct-methods package.

A chiral spherical molecular assembly held together by 60 hydrogen bonds
TL;DR: In this article, a chiral spherical molecular assembly held together by 60 hydrogen bonds is presented, which is able to self-assemble and maintain its structure in apolar media and to encapsulate guest species within a well defined cavity that possesses an internal volume of about 1,375 cubic feet.
