The transition is both displacive and order-disorder involving mainly conformational changes of the organic chain [NH3(CH2)5NH3]2+ coupled with distortion of the TlCl6 octahedra. This behaviour and the crystal dynamics will be discussed and compared with those found in the literature for ...
Preparation of ethyl 3-(2-((4-carbamimidoylphenylamino)methyl)-l-methyl-N- (pyridin-2-yl)-IH-benzo[d]imidazole-5-carboxamido) propanoate of Formula (ll)using N-acetyl cysteine 10 g (0.020 mol) of ethyl 3-(2-((4-cyanophenylamino)methyl)- l-methyl-N- (pyridin-2-yl)-IH- benzo[d...
To a solution of compound1(313 mg, 1.04 mmol) in MeOH (6 mL) was added hydrazinemonohydrate (0.1 mL, 1.67 mmol) at 0°C.After being stirred at same temperature for 3h, the solvents were removed invacuo and the residue was re-dissolved into water (10 mL). The pH ofsolution was th...
Interestingly, although the reaction of [PtCl2(CH3CN)2] with ammonia has been known for more than a hundred years [32], the true nature of the product, [Pt(NH3)2(HNC(NH2)CH3)2]Cl2·H2O (HNC(NH2)CH3 is acetamidine) was revealed only in the 1960s by the X-ray structure analysis...
A virgin sample of polycrystalline (C10H21NH3)2ZnCl4 shows two phase transitions, at 284 K and 363 K. In the low-temperature phase threefold reorientations of methyl and NH3 groups dominate the nuclear magnetic resonance relaxation results. The motion of the NH3 groups can be described as a...
The present article is devoted to the characterization of the structural phase transitions of the [CH3NH3][Co(COOH)3] (1) perovskite-like metal–organic compound through variable-temperature single-crystal neutron diffraction. At room temperature, compound 1 crystallizes in the orthorhombic space group...
A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.

Pandanus odorifer (Forssk) Kuntze grows naturally along the coastal regions and withstands salt-sprays as well as strong winds. A combination of omics approaches and enzyme activity studies was employed to comprehend the mechanistic basis of high salinit
Due to the problems of physical storage methods, chemical storage methods based on using another easily transportable hydrogen-containing compound, which in turn produces H2 by chemical reaction, may be more favored. Ammonia (NH3) is currently one of the most promising H2 carriers. It can form ...
