The various ions and molecules in the structure are linked through N—H⋯O, N—H⋯N and N—H⋯S hydrogen bonds and C—H—π inter­actions into a three-dimensional framework

Bis(4-amino­pyridinium) tetra­chlorido­cobaltate(II)

In the title compound, (C5H7N2)2[CoCl4], the cobalt(II) ion is coordinated by four chloride ions in a slightly distorted tetra­hedral geometry. The crystal packing is stabilized by inter­molecular N—H⋯Cl hydrogen bonding, forming a three-dimensional network. The crystal was a non-merohedral twin emulating tetra­gonal symmetry, but being in fact ortho­rhom­bic

Growth, XRD, Spectroscopic, Hardness and SHG studies of L-asparagine monohydrate single crystals

ABSTRACT Single crystals of L-asparagine monohydrate (LAM) have been grown by slow evaporation solution growth technique. Single crystal X-ray diffraction analysis was employed to identify the cell parameters. The reflection planes of LAM crystal were confirmed by the powder X-ray diffraction study and diffraction peaks were indexed. Functional groups of the sample were identified by FTIR analysis. Optical properties such as optical transmittance and second harmonic generation were also studied on the grown LAM crystals. The soft nature of LAM crystal was checked by measuring the microhardness test

Analisis Emisi Gas Rumah Kaca (Grk) dan Pemetaan Zona Emisi Menggunakan Gis (Geospasial Information System) di Kabupaten Pringsewu, Lampung

Emisi gas rumah kaca (GRK) menjadi perhatian seluruh dunia, baik itu dalam proses pengurangan ataupun pencegahan. Emisi gas rumah kaca (GRK) dapat dihasilkan dari beberapa aktifitas seperti pertanian, peternakan, transportasi dan yang tidak kalah penting dan menjadi perhatian dunia yaitu akibat dari pembakaran hutan. Kabupaten Pringsewu merupakan hasil pemekaran, sehingga potensi emisi gas rumah kaca (GRK) yang dihasilkan relatif lebih besar dibandingkan dengan kabupaten lainnya, kabupaten Pringsewu merupakan lumbung padi di provinsi Lampung. sehingga perlu dilakukan analisis emisi gas rumah kaca (GRK) pada sektor pertanian dan peternakan. Penelitian ini bertujuan menganilisis emisi gas rumah kaca (GRK) dan pemetaannya menggunakan GIS. Beban emisi gas rumah kaca (GRK) di Kabupaten Pringsewu dari sektor pertanian sebesar 79,49 Gg Ton CO2 –Eq/Tahun, dan sektor peternakan sebesar 23,99 Gg Ton CO2 –Eq/Tahun. Total beban emisi gas rumah kaca (GRK) kabupaten Pringsewu adalah sebesar 103,49 Gg Ton CO2 –Eq/Tahun

4-Aminopyridinium 5-carboxypentanoate monohydrate

In the title hydrated salt, C5H7N2+·C6H9O4−·H2O, the carboxy H atom is disordered over two positions with equal occupancy. In the crystal, O atoms of the 5-carboxypentanoate anion link the 4-aminopyridinium cations and water molecules into a three-dimensional network via N—H...O hydrogen bonds. The crystal structure is further consolidated by O—H...O hydrogen bonds involving the anion and the solvent water molecule

Oxalic acid incorporated acetamide single crystal growth dynamics, characterization, NLO and antimicrobial activities via shock wave treatment

Shock waves are applied to non-linear optical materials, particularly organic materials, due to their fast response in electro-optic switches and high nonlinear efficiency. At room temperature, an acetamide-doped oxalic acid single crystal has been grown using the slow evaporation method among other crystal growth techniques. Single crystal oxac applies to shock waves in steps of 50 and 100 shock waves to the tail or the material properties without altering the original crystal system. The grown and shock wave treated crystals of OXAC were structurally identified by X-ray diffraction and Fourier transform infrared spectroscopy,UV–Visible and Photoluminescence spectral analysis, nonlinear optical activity (NLO) studies. The antimicrobial studies such as antibacterial and antifungal activities of the grown crystals of oxalic acid, OXAC and OXAC with 50 and 100 shocks were performed and the obtained results were discussed. From we declared results, we state that the post shock wave induced OXAC crystal is enhancing properties of NLO, antimicroibial studies relatively pre shock wave induced OXAC crystal and reflected in structural and optical studies

Octaakis(4-aminopyridine)-1κ4N1,2κ4N1-aqua-2κO-μ-carbonato-1:2κ3O,O′:O′′-dinickel(II) dichloride pentahydrate

In the title compound, [Ni2(CO3)(C5H6N2)8(H2O)]Cl2·5H2O, one of the the NiII ions is six-coordinated in a distorted octahedral geometry, with the equatorial plane defined by four pyridine N atoms from four aminopyridine ligands, the axial positions being occupied by one water O and a carbonate O atom. The other NiII ion is also six-coordinated, by four other pyridine N atoms from four other aminopyridine ligands and two carbonate O atoms to complete a distorted octahedral geometry. In the crystal structure, molecules are linked into an infinite three-dimensional network by O—H...O, N—H...Cl, N—H...O, O—H...N, C—H...O, C—H...N and C/N—H...π interactions involving the pyridine rings
