Adsorption structure of dimethyl ether on silicalite-1 zeolite determined using single-crystal X-ray diffraction

S. Fujiyama, S. Seino, N. Kamiya, K. Nishi and Y. Yokomori

Synopsis: The most stable sorption site of dimethyl ether on silicalite-1 is the sinusoidal channel. The configuration of guest molecules (linear or bent) plays an important role in determining where the stable sorption site is situated.

The trimorphic structure of N,N'-bis(5-methylsalicylidene)-4-methyl-1,3-phenylenediamine

M. T. Kaczmarek and M. Kubicki

Synopsis: Three crystal forms of the new Schiff base ligand, N,N'-bis(5-methylsalicylidene)-4-methyl-1,3-phenylenediamine, have been found in the course of the synthesis of its complexes with rare earth metals. These forms have different numbers of symmetry-independent molecules (Z' = 1, 3 and 4); only weak intermolecular interactions are involved in the crystal structure as the strong hydrogen bond donors are engaged in relatively strong intramolecular O-H...N bonds.

Experimental and theoretical investigation on the compression mechanism of FeF3 up to 62.0 GPa

F. Zhu, X. Lai, X. Wu, Y. Li and S. Qin

Synopsis: VF3-type FeF3 is predicted to become unstable above 51 GPa, as the result of enhanced structural distortion caused by development of octahedral elongation along the a axis.

Succinate esters: odd-even effects in melting points

S. Joseph and R. Sathishkumar

Structural aspects of intermolecular interactions in the solid state of 1,4-dibenzylpiperazines bearing nitrile or amidine groups

M. Rezler, T. Zolek, I. Wolska and D. Maciejewska

Synopsis: X-ray diffraction analyses for new pentamidine analogs are presented: 1,4-bis(4-cyanobenzyl)piperazine (1) crystallizes in the triclinic space group (P\bar 1) and 1,4-bis(4-amidinobenzyl)piperazine tetrahydrochloride tetrahydrate (2) in the monoclinic space group (P21/n) revealing a complex system of hydrogen bonds for (2).

Solid-state transformation of nanocrystalline phyllomanganate into tectomanganate; influence of initial layer and interlayer structure

S. Grangeon, B. Lanson and M. Lanson

Synopsis: Synthetic vernadite was equilibrated at pH values ranging from 3 to 10 and its crystal structure elucidated using X-ray diffraction on fresh samples and on samples aged for up to 8 years. The main structural transformation with time is related to the migration of Mn3+ from the octahedral layer to the interlayer. For low pH samples, which initially contain a higher number of interlayer Mn3+, this transformation leads to a tunnel-like cryptomelane structure (2 × 2 tunnel size).

Prediction of possible CaMnO3 modifications using an ab initio minimization data-mining approach
