The title compound, C(15)H(10)ClNO(4), belongs to the class of 1,2-diketones, which have important applications in both synthetic organic chemistry and supra-molecular chemistry. A dihedral angle of 9.03 (1)° is found between the mean planes of the two benzene rings. C-H⋯O inter-actions help to stabilize the crystal structure.

Ten chromite ores from ophiolite complexes in SE Iran were analyzed mineralogically by XRD, chemically by XRF, and mineral chemistry by EPMA. The identified paragenesis of silicate minerals of chromite ores with the X-ray diffraction is pronounced differently. It consists of secondary phases formed as serpentine, Cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...

Augmented Reality (AR) is a computer related research area that allows users to see views of the real world enhanced with text and virtual information. AR with 3D models can be used as an educational aid to help students gain spatial intuition. This intuition is very useful in many disciplines like, for example, Inorganic Chemistry. We present in this paper an AR system for teaching spatial rel...

Basic concepts of crystal growth and their practical use to semi-quantitatively estimate growth processes are explained: surface energy and free energy, driving force of crystallization, atomically rough vs smooth interface structure and the corresponding normal vs layer-by-layer growth modes, application of the activated complex concept to derive kinetic coefficient characterizing crystal grow...

The synthesis and X-ray crystal structures of copper(II) nitrate, copper(I) iodide and zinc(II) bromide complexes of the chiral ligand 2 are described.

Three dimensional pharmacophore models can be considered as an ensemble of steric and electronic features in space, which are necessary to ensure intermolecular interaction with a specific target in order to trigger or to block biological activity [1]. By identifying these features, a 3D pharmacophore model can be built in order to screen multi-conformatorial databases with the aim to detect co...

stituents which may facilitate the formation of stable radicals and acceptor species [1 ], In such a context we considered the 1,2-dicyanimino derivative [C4 0 2(NCN)2]2_, henceforth CMCB2because such a group should have at least some of the required properties [2], The very heavy T1 cation had to be accepted, because it was the only one which gave suitable crystals. Owing to the very scanty in...

Synthetic manipulations were carried out with the aim of obtaining an advanced linear fragment for production of thermotropic liquid crystals. The chiral fragment synthesised was introduced in a tolanbenzoate mesogenic core by coupling of Sonogashira. The nal chiral tolans showed smectic A and C and nematic liquid crystalline phases. The crystallographic structure of lactone from (-) menthone i...

In recent papers, there has been a lively exchange concerning theories for enzyme catalysis, especially the role of protein dynamics/pre-chemistry conformational changes in the catalytic cycle of enzymes. Of particular interest is the notion that substrate-induced conformational changes that assemble the polymerase active site prior to chemistry are required for DNA synthesis and impact fidelit...
