Gyration and Permittivity of Ethylenediammonium Sulfate Crystals

Ethylenediammonium sulfate (EDS) crystals were grown from aqueous solution and cleaved into thin (100-500 micron) plates. The 422 point group of EDS was confirmed by X-ray diffraction. The constitutive relations of EDS crystals were determined through generalized ellipsometry with an instrument that uses four photoelastic modulators (4PEM). The optical rotation at 500 nm, for example, was + 22.9°/mm along the optic axis and - 12.1°/mm perpendicular to the optic axis for the P41212 crystals. Enantiomorphous twins frequently form across the (001) plane. Mirrored halves must be separated by cleavage in advance of optical measurements. Chirality 28:460-465, 2016.

Four new CuI/AgI-based coordination compounds containing 2-mercapto-5-methyl-1,3,4-thiadiazole: Synthesis, crystal structures and fluorescence properties

Effectively constructing CuI/AgI-based coordination polymers containing Hmthd ligands is a challenging work, here, four new coordination compounds [Cu(Hmthd)2Cl]n (1), [Cu3(mthd)2Br]n (2), [Ag(mthd)]n (3) and [Ag2(mthd)I]n (4) have been obtained by reactions of the corresponding metal salts and 2-mercapto-5-methyl-1,3,4-thiadiazole (Hmthd) ligand under solvothermal conditions. All the compounds were fully characterized by single-crystal X-ray diffraction, elemental analysis, IR spectrum, thermalgravimetric analysis and powder X-ray diffraction. Compound 1 is a mononuclear coordination compound, in which two neutral Hmthd molecules and CuCl unit are coplanar. In compound 2, the anionic [CuBr(mthd)]22– units and one-dimensional coplanar cationic {[Cu2(mthd)]+}n chains are connected to each other to form a two-dimensional layered structure. In compound 3, two different one-dimensional puckered [Ag(mthd)]n chains are connected to each other to form a two-dimensional irregular layered structure, in which a (AgS)n chain constructed by staggered Ag3S3 rings is observed. Compound 4 is a two-dimensional double layer coordination framework containing a two-dimensional inorganic (Ag2IS)n double layer. Compound 4 shows the apparent yellow emission with the maximum at 551 nm while exciting at 333 nm, and displays sensitive luminescence quenching response to nitrobenzene with quenching constant (Ksv) of 5.07 × 103 M?1 and detection limit of 5.33 × 10?6 M. This research provides a new strategy to construct the CuI/AgI-based coordination compounds containing Hmthd ligands with extended structures through the synergistic effect of (mthd)- and halide ions.

PROCESS FOR ISOLATION OF AN ORGANIC AMINE

The invention relates to a process for the isolation of an organic amine from a composition comprising the organic amine and an acid, or a salt of the organic amine and the acid, wherein the process comprises steps wherein ammonia or hydrazine is added to the composition thereby forming a multi-phase system comprising an organic amine -rich phase and an acid-rich phase, the organic amine-rich phase and the acid-rich phase obtained in step (i) are separated, and the organic amine is isolated from the organic amine -rich phase.
