Synergy between transmission electron microscopy and powder diffraction: application to modulated structures

D. Batuk, M. Batuk, A. M. Abakumov and J. Hadermann

Synopsis: Using examples of anion-deficient perovskites modulated by periodic crystallographic shear planes, it is demonstrated what kind of local structural information can be obtained using various transmission electron microscopy techniques and how this information can be implemented in the crystal structure refinement against the powder diffraction data.

Accepted 16 March 2015

Neutron Laue and X-ray diffraction study of a new crystallographic superspace phase in n-nona­decane/urea

S. Zerdane, C. Mariette, G. McIntyre, M. Lemée-Cailleau, P. Rabiller, L. Guérin, J. Ameline and B. Toudic

Accepted 27 February 2015

Structure of the mixed-metal carbonate KAgCO3 revisited: order-disorder (OD) polytypism and allotwinning

P. Hans, B. Stöger, M. Weil and E. Zobetz

Synopsis: KAgCO3 is polytypic and crystallizes as allotwins (oriented associations of non-equivalent polytypes) with highly ordered domains.

Accepted 26 February 2015

Resonance-stabilized partial proton transfer in hydrogen bonds of incommensurate phenazine-chloranilic acid

L. Noohinejad, S. Mondal, S. I. Ali, S. Dey, S. van Smaalen and A. Schönleber

Synopsis: Correlated variations of chemical bonds demonstrate stabilization by the resonance of the chloranilic acid anion. Proton transfer in some of the intermolecular hydrogen bonds is responsible for the ferroelectic properties.

Accepted 25 February 2015

Synthesis and structural elucidation of new complexes of 2,4- and 3,5-di­methyl di­phenyldi­thiophosphates with cobalt(II)

S. Kumar, R. Khajuria, A. K. Jassal, M. S. Hundal and S. K. Pandey

Synopsis: New cobalt(II) complexes of disubstituted diphenyldithiophosphates with donor ligands have been synthesized and structurally characterized by elemental analyses, IR and single-crystal X-ray analyses. Single-crystal X-ray diffraction analysis reveals a six-coordinated distorted octahedral geometry for the CoS4N2 chromophore, defined by two chelating dithio anions and two N-donor ligands.

Accepted 23 February 2015

Cocrystals of 6-chlorouracil and 6-chloro-3-methyl­uracil: exploring their hydrogen-bond-based synthon motifs with several triazine and pyrimidine derivatives

V. Gerhardt and E. Egert

Synopsis: Two chlorine-containing uracil derivatives have been cocrystallized with several triazine and pyrimidine derivatives. Six cocrystals and two (pseudo-) polymorphs were obtained with two-dimensional layers mainly promoted by hydrogen bonds.

Accepted 18 February 2015

Lack of a threefold rotation axis in [alpha]-Fe2O3 and [alpha]-Cr2O3 crystals

M. Stekiel, R. Przenioslo, I. Sosnowska, A. Fitch, J. B. Jasinski, J. A. Lussier and M. Bieringer

Synopsis: The symmetry of the magnetic ordering of [alpha]-Fe2O3 and [alpha]-Cr2O3 is found to be monoclinic and not trigonal, so the symmetry of their crystal structures should be also monoclinic. This conclusion is supported both by experimental X-ray powder diffraction studies as well as by theoretical arguments.

Accepted 19 January 2015

First experimental charge density study using a Bruker CMOS-type PHOTON 100 detector: the case of ammonium tetraoxalate dihydrate. Addendum

K. N. Jarzembska, R. Kaminski, L. Dobrzycki and M. K. Cyranski

Synopsis: Addendum to Jarzembska et al. [Acta Cryst. (2014), B70, 847-855].
