We report for the first time, synthesis and X-ray diffraction studies of single crystals BeF(2). The were obtained during sublimation amorphous BeF(2) under static reduced pressure. crystallizes in chiral trigonal space group P3(1)21. A single-crystal study on these shows that each Be atoms is bonded to four F atoms, two with associated Be-F bond distances 1.5420(13) 1.5471(13) Å, showing an almost regular tetrahedron. infrared spectrum recorded at room temperature distinct peaks around 770...

α-cyanostyrenes bearing a pyrene scaffold are synthesized and characterized using spectroscopic techniques. The pyrenyl styrenes weakly emissive in solution state but show enhanced emission water due to the formation of aggregates. restrictions intramolecular rotations, increased π-π interactions contribute strong dye molecules aggregated state. aggregates, its size morphological changes was investigated by scanning electron microscopy (SEM) dynamic light scattering (DLS) studies....

Ferrimagnetische Wechselwirkungen zwischen MnII und CrIII wurden beim dreidimensional-polymeren, helicalen Komplex K0.4[Cr(CN)6][Mn(S)-pn](S)-pnH0.6 beobachtet (pn=1,2-Diaminopropan); dabei liegt die Néel-Temperatur mit 53 K relativ hoch.

Self-assembly formation of a bridging ligand and chiral auxiliary with metal center, in general, gets dominated by the former interaction. We report here that introduction weak noncovalent interactions, away from can manifest molecular chirality an into self-assembled structure, strategy useful for observing magnetochiral dichroism effect. Structural details azido bridged copper(II) coordination networks enantiomerically pure, racemic, admixtures benzylamine derivatives are discussed.

Spallation neutron and high-energy X-ray diffraction experiments have been performed to investigate the local structural changes in triphenyl phosphite (TPP) crystalline, glacial, glassy, supercooled liquid phases. The hydrogen/deuterium first-order difference method shows a large increase intensity due additional hydrogen correlations crystalline spectra compared glass at ∼3.0 3.4 Å. These features are shown be largely inter-phenyl ring H−C/H interactions, which probably associated part...

Spallation neutron and high-energy X-ray diffraction experiments have been performed to investigate the local structure of glacial supercooled liquid states in triphenyl phosphite. The observed patterns interpreted using a Reverse Monte Carlo modeling technique. results show that state forms unusually weak intermolecular hydrogen bonds between an oxygen atom connected phenyl ring adjacent aligned approximately antiparallel configuration. is very different from hexagonal crystal which...

In centrosymmetric molecules, like An+[M(CN)6]n- (where A is alkali metal cation), normally all stretching vibrations of cyanide (CN-) shift to high frequency in response nonhydrostatic pressure, whereas, non-centrosymmetric molecules which one axial CN ligand replaced by NO ligand, observes unusual softening only equatorial modes. This effect pronounced when A+ Ag+ with difference coordination ability latter, resulting expression characteristic signature back-bonding. One can correlate this...

The manuscript revolves around an interesting observation of solidification a solution N-((1-((1-ethyl-1H-benzo[d]imidazol-2-yl)methyl)-1H-1,2,3-triazole-4-yl)methyl)aniline (A6) in the NMR tube after 12 h.

Observation and creation of a pro-chiral center is prerequisite in chemical synthesis for generating chiral structures. On the other hand, temporary reversible generation or polar structures using physical forces such as electricity need present technology observing nonlinear behavior. Thus, one can synthesize pro-polar structure, akin to interactions, facilitating chiral/polar structures, novel way designing molecular materials. At room temperature, structure KNO3 anilinium nitrate (AnHNO3)...

Abstract Molecular crystals demonstrate drastically different behavior in solid and liquid state, mainly due to their difference structural frameworks. Therefore, designing of unique structured molecular compound which can work at both these interfaces has been a challenge.
