Crystal structure and intermolecular interaction energy calculation in N,N′-bis(4-iodobenzylidene)-ethane-1,2-diamine [PDF]
A new potentially bidentate Schiff base ligand was synthesized from condensation reaction between ethylenediamine and 4-iodobenzaldehyde. The crystal structure of the compound was studied by single-crystal X-ray diffraction and it was shown that the ...

An X-Ray Investigation of the Nickel-Boron System. The Crystal Structures of Orthorhombic and Monoclinic Ni4B3. [PDF]
The Ni-B system was investigated with x-ray powder and single-crystal methods in the range Ni/sub 3/B to NiB. In addition to the previously known intermediate phases, Ni/sub3/B, Ni/sub 2/B, and NiB, the existence of two other phases, both with the ideal compositions Ni/sub 4/B/sub 3/ but one orthorhombic and the other monoclinic, was established.

Kinetic studies of oxidative coupling of methane on samarium oxide [PDF]
Kinetic behaviour of three samples of samarium oxide (cubic (Sm-1 ), monoclinic (Sm-3) and mixed cubic-monoclinic (Sm 2) ) were studied in the oxidative coupling of methane using a gradientless flow circulation system.

Anisotropy, phonon modes, and lattice anharmonicity from dielectric function tensor analysis of monoclinic cadmium tungstate [PDF]
We determine the frequency dependence of four independent CdWO$_4$ Cartesian dielectric function tensor elements by generalized spectroscopic ellipsometry within mid-infrared and far-infrared spectral regions.

6,7-Dihydro-5H-pyrrolo[1,2-a]imidazole
The crystal structure of 6,7-dihydro-5H-pyrrolo[1,2-a]imidazole, C6H8N2, at 100 K has monoclinic (P21/n) symmetry. The molecule adopts an envelope conformation of the pyrrolidine ring, which might help for the relief torsion tension. The crystal cohesion
