Polymorph II of 2-(2-Ethyl-2,3-dihydro-1-benzofuran-2-yl)imidazolinium Chloride

C. Belin, R. Pena, A. Chauvet, J. P. Ribet and J. L. Maurel

Synopsis: In the title compound (efaroxan hydrochloride), homochiral cationic molecules form chains along the b axis of the triclinic cell via N-H...Cl hydrogen bonds. The furanyl groups are nearly parallel to the a axis and the imidazolinium rings are roughly perpendicular to it.

Formula: C13H17N2O+.Cl-

M. Parvez, P. Kulanthaivel and M. H. Benn

Synopsis: The structure and relative stereochemistry of O-methyldehydronorcacalol, a sesquiterpenoid isolated from Traversia baccharoides Hook f., is established. The hydroxyl group takes part in a bifurcated hydrogen bond, intramolecular with an adjacent methoxy O atom and intermolecular with an acetyl O atom of an adjacent molecule.

Formula: C15H18O3

Redetermination of Monoclinic VOHPO4.2H2O

H. Worzala, T. Goetze, D. Fratzky and M. Meisel

Synopsis: A new synthetic route for the preparation of single crystals of monoclinic VOHPO4.2H2O has been found. The results of the single-crystal structure analysis are compared with those of an earlier X-ray powder structure determination.
