The transformation of a thiocarbonyl compound into an alkene by stepwise treatment with a diazo compound and triphenylphosphane is known as Barton-Kellogg olefination. As a model reaction, 4,4'-dimethoxythiobenzophenone and diazocyclohexane...

Isoguanine nucleosides constructed by different heterocyclic skeletons play a significant role in the context of genetic code expansion, as well as for purine-purine base pairing. However, with respect to structure...

Noncovalent interactions have received much attention in the fields of supramolecular chemistry and crystal engineering. Hydrogen bonding and weak interaction forces affect crystal stacking. Crown-ether-based host-guest inclusion compounds with hydrogen...

Three multicomponent systems, namely, 2,4-diamino-6-phenyl-1,3,5-triazine-nicotinic acid (DAPT-NA), CHN·CHNO, (I), 2,4-diamino-6-phenyl-1,3,5-triazin-1-ium hydrogen malonate (DAPT-MMA), CHN·CHO, (II), and 2,4-diamino-6-phenyl-1,3,5-triazin-1-ium hydrogen (+)-dibenzoyl-D-tartarate (DAPT-DBTA), CHN·CHO, (III), have been synthesized and characterized via single-crystal X-ray...

The newly obtained compound 7-(4-chlorophenyl)-1-hydroxy-5-methylpyrido[3,4-d]pyridazin-4(3H)-one (CPM) was crystallized as two new variable solvates, namely, the dimethyl sulfoxide monosolvate, CHClNO·CHSO (I), and the sesquisolvate, CHClNO·1.5CHSO (II), and their structures were confirmed...

The synthesis, crystal structure, and [2+2] cycloaddition photoreactivity of a halogen-bonded mixed cocrystal is reported. The cocrystal solid solution contains two isosteric donors, namely, 1,4-diiodoperchlorobenzene (CICl) and iodoperchlorobenzene (CICl), along...

The crystal structure of capsaicin (CHNO), or trans-8-methyl-N-vanillylnon-6-enamide, the natural product responsible for the spiciness of chilli peppers, was determined using low-temperature single-crystal X-ray diffraction. The reported crystal structure is...

To date there are very few examples of crystallographically well-documented racemic mimics. The original discovery of this class of crystals occurred at a time when crystallography was in its infancy,...

The synthesis and characterization of six novel coumarin derivatives containing O and S atoms are described here, namely, ethyl 2-oxo-2H-chromene-3-carboxylate, CHO (S1a), ethyl 2-sulfanylidene-2H-chromene-3-carboxylate, CHOS (S2a), ethyl 2-sulfanylidene-2H-chromene-3-carbothioate, CHOS (S3a),...

This collection highlights the diversity and quality of research conducted by Latin American scientists, and emphasizes the interdisciplinary nature of crystallography, highlighting its connections with other research fields and presenting...
