CONVENTIONAL AND NONCONVENTIONAL METHODS OF SYNTHESIS AND GROWTH-STIMULATING ACTIVITY OF 3-CHLORO-N,N-DIETHYL-N-(2-(MESITYLAMINO)-2-OXOETHYL)PROPAN-1-AMINIUM IODIDE

Synthesis of 3-chloro-N,N-diethyl-N-(2-(mesitylamino)-2-oxoethyl)propan-1-aminium iodide (1) was performed by via N-alkylation in conventional conditions and using microwave irradiation and ultrasound activation. The synthesized ionic compound was characterized using IR, 1H and 13C NMR, growth-stimulating activity had been tested for ten varieties and hybrids of sweet sorghum seeds.

Crystal structure of a new hydrate form of the NSAID sodium diclofenac

The crystal structure is reported of sodium 2-[2-(2,6-dichloroanilino)phenyl]acetate 3.5-hydrate or tetra-μ-aqua-κ8 O:O-decaaquabis{μ3-2-[2-(2,6-dichloroanilino)phenyl]acetato-κ3 O:O:O}tetrasodium(I) bis{2-[2-(2,6-dichloroanilino)phenyl]acetate}, {[Na4(C14H10Cl2NO2)2(H2O)14](C14H10Cl2NO2)2} n , which represents a new hydrate form of the NSAID sodium diclofenac (SD). The triclinic unit cell contains one ionic compound with formula Na4(C14H10Cl2NO2)4(H2O)14, in which two symmetry-related carboxylate anions C14H10Cl2NO2 − are bonded to a centrosymmetric [Na4]4+ core cationic cluster, while the others are only hydrogen bonded to the cationic cluster. The conformation for the anions is similar to that found in other diclofenac compounds, and the [Na4(Ocarbox)2(H2O)14]4+ cluster displays an unprecedented geometry, which can be described as an incomplete dicubane cluster formed by face-sharing incomplete cubes. A complex framework of O—H...O hydrogen bonds stabilizes the crystal structure. The herein reported crystal structure for SD·3.5H2O in space group P\overline{1} is different from those previously reported for other hydrates, namely SD·4.75H2O (P21) and SD·5H2O (P21/m).

Rerefinement of the crystal structure of trichloridosulfonium(IV) hexachloridouranate(V), (SCl3)[UCl6]

Single crystals of trichloridosulfonium(IV) hexachloridouranate(V) were obtained from the reaction of uranium(IV) chloride with an excess of disulfur dichloride and studied by single-crystal X-ray diffraction. In comparison with the structure model reported previously [Sawodny et al. (1983). Z. Anorg. Allg. Chem. 499, 81–88.], the lattice parameters and fractional atomic coordinates were determined to a much higher precision, leading overall to an improved structure model. The ionic compound contains trigonal–pyramidal (SCl3)+ cations and slightly distorted octahedral [UCl6]− anions. The structure was refined as an inversion twin with a twin ratio of 4.4:1.

Efficient perovskite solar cells via surface passivation by a multifunctional small organic ionic compound

This work reports an effective surface passivation strategy using the multifunctional organic ionic compound 1-ethylpyridinium chloride in combination with (FAPbI3)0.95(MAPbBr3)0.05.

A new polymorph of ammonium succinate – serendipity in action

Succinic acid has been known since 1546 and was first chemically identified in the mid-19th century. In an attempt to prepare a molecular salt of succinic acid with (S)-(−)-α-methylbenzylamine, we have obtained the second polymorph of the monoammonium salt of succinic acid, NH4 +·C4H5O4 −. The crystal structure determination proves the structure of the ionic compound and the intimate role of the ammonium ion in the structure, which is compared to the earlier described polymorph.
