research papersAbsolute structure of the chiral pyrrolidine derivative (2S)-methyl (Z)-5-(2-tert-butoxy-1-cyano-2-oxoethylidene)pyrrolidine-2-carboxylate, a compound with low resonant scattering
The light-atom compound (2S)-methyl (Z)-5-(2-tert-butoxy-1-cyano-2-oxoethylidene)pyrrolidine-2-carboxylate is an enantiopure coordination partner for cations. Despite its only minor resonant scattering, the absolute structure was determined by a combination of diffraction, CD spectroscopy and theoretical calculations.
research papersA concise and efficient synthesis of amino-substituted (1H-benzo[d]imidazol-1-yl)pyrimidine hybrids: synthetic sequence and the molecular and supramolecular structures of six examples
Syntheses are reported for a series of amino-substituted (1H-benzo[d]imidazol-1-yl)pyrimidines and structures are reported for six products of this type. Multiple hydrogen bonds generate supramolecular structures in two or three dimensions.
research papersPolymorphism and photoluminescence properties of K3ErSi2O7
The crystal structures of two tripotassium erbium disilicate, K3ErSi2O7, polymorphs synthesized by high-temperature flux crystal growth were determined by single-crystal X-ray diffraction analysis. Powder X-ray diffraction, photoluminescence spectroscopy and scanning electron microscopy equipped with an energy dispersive X-ray spectrometer elucidated differences between the two polymorphs.
research papersSynthesis, crystal structure solution and characterization of two organic–inorganic hybrid layered materials based on metal sulfates and 1,4-phenylenediamine
The powder X-ray diffraction technique was used to determine the crystal structures of two new organic–inorganic hybrid materials forming three-dimensional networks composed of alternating organic and inorganic layers. Thermal stability tests of the materials indicated that one is stable up to 537 K and the other is stable up to 437 K.
research papersTwo precatalysts for application in propargylic CH activation
The complexes [Rh(NBD)(DPEPhos)]BF4 and [Rh(COD)(DPEPhos)]BF4·CH2Cl2 {DPEPhos is bis[(2-diphenylphosphanyl)phenyl] ether, NBD is norborna-2,5-diene and COD is cycloocta-1,5-diene} are applied as precatalysts. In addition, the catalytically inactive pentacoordinated 18-electron complex [RhCl(NBD(DPEPhos)] was synthesized, which forms in the presence of chloride in the reaction system.
