The complexity of a structure depends on the nature of the bonding in the crystal and thus on the position of an element in the periodic table. Nearly all metals have simple structures and most of them have their atoms in a close-packed structure. Elements with weakly metallic character tend...
Two kinds of bond length for Bi-Te (Se) are found. They lie in a range between covalent and ionic extremes. The temperature factors of each atom are also estimated. Relations between the crystallographic data and physical properties are discussed....
Structure-Property Relations of Ternary Equiatomic YbTX Intermetallics The equiatomic intermetallic compounds RTX (R = rare earth or actinide metal; T = transition metal; X = element of the 3rd or 4th main group) have attracte... P Rainer,D Johrendt,D Kußmann - 《Cheminform》 被引量: ...
Crystal structure does not necessarily depend on the arrangement of individual atoms, etc.; it is expressed by the distribution of imaginary points reflecting the periodicity in crystals, which are called the lattice points. As shown in Fig. 3.2, the arrangement of all of the lattice points is...
Crystal Structure and Enzyme Kinetics of the ( S )-Specific 1-Phenylethanol Dehydrogenase of the Denitrifying Bacterium Strain EbN1 , ( S )-1-Phenylethanol dehydrogenase (PED) from the denitrifying bacterium strain EbN1 catalyzes the NAD + -dependent, stereospecific oxidation of ( S )-1-p......
The molecular mechanisms of transthioesterification and the overall architecture of the E1–E2–Ub complex during catalysis are unknown. Here, we determine the structure of a covalently trapped E1–E2–ubiquitin thioester mimetic. Two distinct architectures of the complex are observed, one in which ...

31. Other methods rely on comparisons of pair distribution functions32. Some of the well known or recently released software packages include STRUCTURE-TIDY28, CRYCOM30, CMPZ33, XTAL-COMP34, COMPSTRU31, SPAP35, the pymatgen Structure Matcher36, and AFLOW-XtalFinder37. While they all have ...
Using a novel X-ray microcrystallography technique the atomic crystal structure of the cross-β spine of a seven-residue peptide was determined. It was found to be a double β-sheet, where the opposing sheets form an extremely close, zipper-like, match and are stabilized by non-hydrogen inte...
Structure Crystals can be grown under moderate conditions from all 92 naturally occurringelementsexcept helium, and helium can be crystallized at low temperatures by using 25 atmospheres of pressure.Binarycrystals are composed of two elements. There are thousands of binary crystals; some examples are ...
