Crystal structure of pseudoguainolide [PDF]
Acta Crystallographica Section E Crystallographic Communications, 2015 The lactone ring in the title molecule, C15H22O3(systematic name: 3,4a,8-trimethyldodecahydroazuleno[6,5-b]furan-2,5-dione), assumes an envelope conformation with the methine C atom adjacent to the the methine C atom carrying the methyl substituent being the flap atom.

Crystal structure of vancomycin [PDF]
Structure, 1996 Vancomycin and other related glycopeptide antibiotics are clinically very important because they often represent the last line of defence against bacteria that have developed resistance to antibiotics. Vancomycin is believed to act by binding nascent cell wall mucopeptides terminating in the sequence D-Ala-D-Ala, weakening the resulting cell wall ...

The crystal structure of cyclin A [PDF]
Structure, 1995 Eukaryotic cell cycle progression is regulated by cyclin dependent protein kinases (CDKs) whose activity is regulated by association with cyclins and by reversible phosphorylation. Cyclins also determine the subcellular location and substrate specificity of CDKs.

Crystal structure of ruthenocenecarbonitrile [PDF]
Acta Crystallographica Section E Crystallographic Communications, 2015 The molecular structure of ruthenocenecarbonitrile, [Ru(η5-C5H4C[triple-bond]N)(η5-C5H5)], exhibits point group symmetrym, with the mirror plane bisecting the molecule through the C[triple-bond]N substituent. The RuIIatom is slightly shifted from the η5-C5H4centroid towards the C[triple-bond]N substituent.

Crystal structure of fluroxypyr [PDF]
Acta Crystallographica Section E Crystallographic Communications, 2016 In the title pyridine herbicide {systematic name: 2-[(4-amino-3,5-dichloro-6-fluoropyridin-2-yl)oxy]acetic acid}, C7H5Cl2FN2O3, the mean plane of the carboxylic acid substituent and the pyridyl ring plane subtend a dihedral angle of 77.5 (1)°. In the crystal, pairs of O—H...O hydrogen bonds form inversion dimers withR22(8) ring motifs.

SHELXT – Integrated space-group and crystal-structure determination
Acta Crystallographica Section A: Foundations and Advances, 2015 SHELXT automates routine small-molecule structure determination starting from single-crystal reflection data, the Laue group and a reasonable guess as to which elements might be present.
