Anhydrous guanine: a synchrotron study.
Very small crystals of anhydrous guanine (systematic name: 2-amino-1,7-dihydro-6H-purin-6-one), C5H5N5O, were obtained from an attempted solvothermal synthesis of a potassium complex. Data were collected at 120 K using a synchrotron radiation source. There is one essentially planar molecule in the asymmetric unit. Molecules are linked to each other by NÐH N and NÐH O hydrogen bonds to form shee...
متن کاملAmmonium salicylate: a synchrotron study
The structure of the title salt, NH(4) (+)·C(7)H(5)O(3) (-), is stabilized by substantial hydrogen bonding between ammonium cations and salicylate anions that links the components into a two-dimensional array.
متن کاملA synchrotron study of Na2.27Ho7.73(SiO4)6O0.72
A well crystallized powder sample of sodium holmium orthosilicate oxyapatite, Na(2.27)Ho(7.73)(SiO(4))(6)O(0.72), was obtained after mechanical milling and thermal treatment at 1123 K. Crystal structure analysis was performed from the results of Rietveld refinement of the synchrotron diffraction data. As in other rare-earth orthosilicate apatites, sodium cations appear located sharing with holm...
متن کاملGuanine-based photonic crystals in fish scales form from an amorphous precursor.
Starting from disorder: anhydrous guanine crystals compose the photonic arrays responsible for the skin and scale iridescence found in Japanese Koi fish. These guanine crystals were found to form in intracellular vesicles through an amorphous precursor phase. A combined cryo-SEM and synchrotron radiation X-ray diffraction study showed the evolution of the crystals in great detail.
متن کاملThermodynamic Parameters of Cis-Platin and Trans-Platin Complexes with Guanine in Water, A DFT Study
The binding energy and Thermodynamic Parameters of cis- Platinum Di Ammino Chlorine (cis-[Pt(NH3)2Cl]+) and trans- Platinum Di Ammino Chlorine (trans- [Pt(NH3)2Cl]+) complexes withGuanine has been studied by density functional theory (DFT) calculations in water. The bindingenergies (Ebin) of cis- and trans-[Pt(NH3)2ClG]+ are calculated to be 79.38 kcal/mol and 74.98kcal/mol, respectively. The b...
