Assembly with Multinuclear Silver-Ethynediide/-Ethynide Supramolecular Synthons [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
Over the past 15 years, our group has conducted a systematic investigation on the synthesis and structural characterization of a series of silver(I) double and multiple salts containing silver carbide Ag2C2n (n = 1, 2), in which the all-carbon dianion ethynediide C22-is generally capsulated inside a polyhedral Agm (m = 6-10) cage, whereas C42-exhibits ...

Crystal structures of two isomers of 1-(naphthalen-1-yl)ethanol

Acta Crystallographica Section E: Crystallographic Communications
Crystal structures, Hirshfeld surfaces and energy lattices of (S)-1-(naphthalen-1-yl)ethanol (1) and (R)-1-(naphthalen-2-yl)ethanol (2), both C12H12O, were studied to understand much the lower crystallization propensity of the latter. In both structures,

From molecules to materials : Engineering new ionic liquid crystals through halogen bonding [PDF]

, 2018
Herein, we demonstrate that a bottom-up approach, based on halogen bonding (XB), can be successfully applied for the design of a new type of ionic liquid crystals (ILCs).

A systematic structural study of halogen bonding versus hydrogen bonding within competitive supramolecular systems

IUCrJ, 2015
As halogen bonds gain prevalence in supramolecular synthesis and materials chemistry, it has become necessary to examine more closely how such interactions compete with or complement hydrogen bonds whenever both are present within the same system.

Molecular and supramolecular chemistry of mono- and di-selenium analogues of metal dithiocarbamates [PDF]

, 2018
This bibliographic review summarises the coordination chemistry of mono- and diselenium analogues of metal dithiocarbamate ligands, [RRꞌNCS2]-, as revealed by X-ray crystallography and spectroscopy (77Se NMR and infrared).

Crystal structure of (Z)-ethyl 3-[2-(5-methyl-7-nitro-1H-indole-2-carbonyl)hydrazinylidene]butanoate

Acta Crystallographica Section E: Crystallographic Communications, 2015
The reaction of 5-methyl-7-nitro-1H-indole-2-carbohydrazide with ethyl acetoacetate yielded the title molecule, C16H18N4O5, in which the indole ring is almost planar, with the greatest deviation from the mean plane being 0.006 (2) Å.
