The title compound 1 has been prepared from the condensation product of a silyl protected amino-oxazoline lactam (3) and Cbz-protected L-tryptophan (4) after hydrogenolysis of the carboxybenzyl protection group. The synthesis and crystal structure of 1 is described. The compound crystallized from DMSO in the monoclinic system, P21 space group with unit cell parameters a = 9.4029(25), b = 6.2828...

The urea adduct with the guests of m-nitrobenzoic acid, m-nitroaniline and p-xylene mixtures by adductive crystallization was successfully grown by slow evaporation method. The single crystals obtained were non-hygroscopic and good in size. The crystal structure of the grown crystal has been determined, and it belongs to the monoclinic system with centrosymmertic space group P21/c. Fourier tran...

Nanostructured As2Ni3O8 samples were synthesized via facile solid-state reactions at 850 and 950 °C for 8h using As2O3, Ni(CH3COO)2.2H2O and Ni(NO3)2.6H2O raw materials. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and fourier-transform infrared (FTIR) spectroscopy. The rietveld analyses showed that the obtained materials were crystallized well i...

The discovery of the monoclinic Cu5Sn2S7 phase adds a high mobility member to Cu–Sn–S diagram and demonstrates how crystal structure can be advantageously manipulated design novel compositions for energy-oriented applications.

Iron oxides are fundamentally important compounds for basic and applied sciences as well as in numerous industrial applications. In this work we report the synthesis and investigation of a new binary iron oxide with the hitherto unknown stoichiometry of Fe7O9. This new oxide was synthesized at high-pressure high-temperature (HP-HT) conditions, and its black single crystals were successfully rec...

The structures of the liquid, glass ~i.e., amorphous!, rotator-phase ~RP! crystal, orientational glass ~OG!, and the stable ~monoclinic! crystal phases of ethanol are investigated by means of neutron and x-ray diffraction. The RP crystal and OG phases show an intermediate kind of disorder between that of the fully disordered glass and liquid phases and that of the stable crystal. The Bragg patt...

N,N′ -Dipropyl-N,N,N′ ,N′-tetramethyl-1,2-ethylenediammonium dichloride (1) and dibromide (2) were prepared by the reaction of N,N,N′,N′-tetramethyl-1,2-ethylenediamine and the corresponding 1-halopropane. The structures of the compounds were characterized by single-crystal X-ray diffraction. 1 · 2H2O crystallizes in the triclinic crystal system, space group P1, with Z = 1, and 2 in the monocli...
