The Structure of the Benzene Ring

  title={The Structure of the Benzene Ring},
  author={Kathleen Dame Lonsdale},
AN X-ray examination of hexa-methyl benzene, C6(CH3)6, recently completed, has led to certain definite and fundamental conclusions concerning the symmetry and form of the benzene ring. 

Structure Determinations of Increasing Complexity

I have had the opportunity of examining by X-rays the crystals of ergosterol and certain of its irradiation products, recently described by a team working at the National Institute for Medical

Unusual Coordination of Naphthalene in the Polynuclear Heteroligand Ytterbium–Erbium Complex

The reaction of Cp3Er with Yb(C10H8)(THF)2 in tetrahydrofuran affords hetero- and homoleptic complexes CpYb(C10H8)(THF)2 (I), [Er(Cp)H(THF)]2 (II), and Cp2Yb(THF)2 (III). Their structures are

Peritectic phase transition of benzene and acetonitrile into a cocrystal relevant to Titan, Saturn's moon.

The phase diagram of mixtures of acetonitrile and benzene is reported, and the stability of the structure under liquid ethane is tested, providing new insights into the structure and stability of potential extraterrestrial minerals.

A Simple and Exact Interpretation of the Bond Lengths and Stacking Distances in Benzene and its Dimers in Terms of Atomic Covalent Radii

The structure of benzene and the stacking distances in its dimers have long been of interest for scientists. As the various rigorous approaches over the years to understand these have been

The thermochemistry and crystallography of the metal tris-acetylacetonates

Due to conflicting reports concerning the crystallographic properties of metal tris-acetylacetonates, we decided to explore the thermochemistry and crystallography of these substances to ascertain

The associated magnetic moments of the periodic rotational motion of methyl groups in hexamethylbenzene (C6(CH3)6) were recently identified to contribute to its overall magnetic susceptibility. Those

Origins and historical development of X-ray analysis

The article presents a brief account of the events leading to the discovery of X-ray diffraction in 1912. The early history and development of the science of X-ray analysis is then outlined and the

Development of X-Ray Powder Diffraction Methods for Biomolecules

The comparable order of magnitude between interatomic distances in a crystal and the wavelength of X-rays make X-ray crystallography the ideal analytical tool to gain insight into the structure of

Problems of Organic Structures

In organic chemistry there are two basic and complementary problems, analysis and synthesis. By analysis the chemist attempts to find the number, kind and spatial arrangement of the atoms in his

Distortions, deviations and alternative facts: reliability in crystallography

In this text based on the 2018 Lonsdale lecture, instructive examples are given of unusual and unexpected structures derived from X-ray crystallography, not all of which are genuine results.
