The crystal structure of boron tetrathiophosphate BPS4 was reinvestigated using singleヽrystal X‐ray diffraction. The structure shows unidimensional chains similar to SiS2 as structural motifs. BPS4 crystallizes in the orthorhombic space group Ibam (no. 72), with a = 5.6173(3), b = 8.9929...

THE CRYSTAL STRUCTURE OP BORON TRIFLUORIDE DIHYDRATEThe early observation by KUnkenberg & Ketelaar (1935) that the x-ray diffraction pattern of EF3.2H2o is very similar to those of NH4 BF$ and NLi4CLO4 suggested that the former compound is isomorphous with the latter compounds, and so is ...
The Crystal Structure of Boron Carbide Several crystals of boron carbide, grown from molten Cu, Pt, and Pd solutions using natural occurring as well as isotopically enriched boron, give essentially identical values for the lattice parameters. These parameters are consistent w... HK Clark,JL Hoard...
The crystal structure of three different samples of melt-grown β-rhombohedral boron has been reinvestigated. There are 20 different symmetry-equivalent atomic positions in the unit cell, four of which have not been previously reported. Six of the 20 are partially occupied. The hexagonal unit cell...
the driving force for the crystallization should be due to the intermolecularπ–πinteraction32,33between azobenzene group and imidazole cation. In order to confirm the crystal structure of [OMIm]AzoO that is grown in [OMIm]PF6, the crystals as a form of rectangular fibers were characterized by...
decade, many important discoveries, e.g., transparent insulating phase of sodium2, superhard M-carbon3,4, partially ionic high-pressure form of elemental boron5, and superconducting sulfur hydride H3S with the record highTc203 K6,7, etc., were triggered by crystal structure prediction methods...
The IR spectrum confirms the presence of BO 3 groups and the UV–vis–IR diffuse reflectance spectrum exhibits this compound has a short UV cut-off edge below 200nm. Band structures and density of states were calculated. 展开 关键词: beryllium, Be boron, B cesium, Cs structure (solids and...
