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...
So far, more and more interest has been made in the study of the inorganic metals facet-dependent catalytic activities and inorganic metal oxide nanocatalysts, as it is known that the arrangement of atoms on the surface is directly correlation with catalytic reactivity. Inorganic metal oxide ...
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 ...
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 ...
The indium atoms are coordinated by sulfur atoms with tetrahedral as well as octahedral arrangement, while the coordination numbers of the two crystallographically independent M atoms are nine and ten. A special feature of these solids is the slightly distorted joint ccp arrangement of the sulfur...
