The O atoms on the surface diffuse into the bulk with increasing temperature, but the diffusion is blocked by the N atoms, in the case of the NO-adsorbed surfaces under any condition.doi:10.1016/s0039-6028(99)00146-6H. Miki aK. Irokawa a...
Hydrogen atoms are not shown. In the Azo1 crystal, two of the four molecular units project semi-parallel into the cell along the c direction (Figure 7). These two molecules interact with each other through mutually intercalated H-O···H-C hydrogen bonds (HB) with a distance of 2.692...
C-5' C-7', C-8', C-9' C-11', C-12' The assignment of the relative configurations of the atoms attached to C-2, C-4', and C-8' was determined by the 13C NMR (Table 1) chemical shifts (measured in CDCl3) when compared to the previously reported data of crassumtocopherol A...
The crystal structure consists of OsO 5 trigonal bipyramids separated by sodium cations, and is isostructural to Na 3 ReO 5 . The osmium atoms adopt a packing analogous to ccp, where Na occupies the octahedral and tetrahedral vacancies, so the cation structure is derived from the Li 3 Bi ...
The crystal structure of Hg 3 AlF 6 O 2 H, trimercury(II) aluminium hydrogen hexafluoride dioxide, can be derived from a slightly distorted cubic close-packed (ccp) arrangement of the metal atoms, where three quarters of the positions are occupied by Hg atoms and one quarter by Al ...
of H2O2 in the absence of CycII to prevent peroxidase activity. We observe strictly heme-mediated oxidation, implicating sequential cycles of binding and reduction of H2O2 at Ccp1's heme. This results in the incorporation of 20 oxygen atoms predominantly at methionine and tryptophan residues. ...

These tetrahedra are well defined in these crystal structures because the bond valences between A and X are essentially higher than the bond valences between A and atoms from other structural units. According to their size, anion-centered tetrahedra may be subdivided into large and small ...
In all cases, the Sb atoms are in a fully ordered ccp or hcp arrangement. In between are the Cu and Li atoms. They exhibit an extensive disorder due to both, mixed and partial occupations making the alloy system Cu-Li-Sb a candidate for electrode materials to ...
