The strong hydrogen bonds link molecules in finite chains, with hydroxyl O atoms acting as both donors and acceptors of hydroxyl H atoms. O hydrogen bonds and a two-centre iodo. A layer can assume four different but equivalent positions with respect to its nearest neighbor. A non-conventional mechanism of strain relaxation has been proposed, which is competitive with respect to the usual formation of misfit dislocations. O hydrogen bonds to carboxylate groups.
Similar discrepancies are found for the high-pressure polymorph of phenanthrene, which is here re-investigated in greater detail.
It has been found that the values of bond-valence parameters decrease with increasing lanthanide atomic number for coordination compounds.
The chains are linked into a ribbon by a second set of ND. Rods of weak diffuse scattering confirm the stacking model.
O distance in the OD. Its mechanism is driven by the hydrogen ordering between the partially ordered TDP-II state and the completely ordered TDP-III state.
Molecular dipole moments and electrostatic potentials obtained from invariom modelling are discussed and compared with results from ab initio theoretical calculations.
Despite the great diversity of CN and types of coordination polyhedra, the volume of the VD polyhedron was found to depend only on the identity of the Ln atom and its oxidation state. The near-neighbor relations between molecules remain unchanged through all twin boundaries. Given the important disorder observed in the latter compound, only a combination of non-harmonic waves, crenel functions and TLS tensors offered a good modelling of the structure. Het is belangrijk dat dat verandert - vandaar die 'Day Against DRM'. Structural Science has broad chemical coverage, encompassing metals and alloys, inorganics and minerals, metal-organics and purely organic compounds. O hydrogen bonds, two two-centre iodo.
Although neutron diffraction experiments are the preferred source of this information, for a variety of reasons they are possible only for a minority of materials of interest. O contact formed to a carboxylate in another layer.
