Structure of monoclinic nickel(II) sulfate hexahydrate
Cristallisation dans C2/c avec affinement jusqu'a 0,04. Chaque atome de nickel a une coordination octaedrique (avec 6 molecules d'eau) avec une longueur moyenne de liaison Ni−O de l'ordre de 2,048 A
Redetermination of sodium cerium(III) sulfate monohydrate, NaCe(SO4)2.H2O.
The data establish that the lack of correction for absorption in the previous study of the Ce salt, rather than some intrinsic property of theCe salt, is responsible for the displacement parameter discrepancies.
Redetermination of the structures of 1-naphthoic acid and 2-naphthoic acid.
Results indicated that the proton, but not the O atoms, is disordered in the carboxylic acid group of 2-naphthoic acid.
γ-Aminobutyric Acid: a Novel Tetragonal Phase
In the tetragonal phase of γ-aminobutyric acid, C4H9NO2, the single type of molecule adopts a partially folded zwitterionic form. Whereas in the previously characterized monoclinic phase the
2-Naphthoic acid at 153 K.
Comparisons of the geometric parameters of the carboxyl groups at 296 and 153 K suggest progress toward a fully ordered structure at the lower temperature, as in the room-temperature study.
Structure of phenoxathiin (phenothioxin), C12H8OS, at 223 K.
The phenoxathiin molecule is constituted of two very nearly regular planar hexagonal carbocyclic (benzenoid) rings joined to a non-planar heterocyClic ring.

The title aldehyde, C15H14O3, crystallized in the centrosymmetric space group P2(1)/c with one molecule in the asymmetric unit with six significant intermolecular C-H...O interactions link a molecule directly to six neighbors and form a three-dimensional network.
