Molecular structure exhibiting

All gases and most liquids of simple molecular structure exhibit what is termed Newtonian behaviour, and their viscosities are independent of the way in which they are flowing. Temperature may, however, exert a strong influence on viscosity which, for highly viscous liquids, will show a rapid decrease as the temperature is increased. Gases, show the reverse tendency, however, with viscosity rising with increasing temperature, and also with increase of pressure. 

An organometallie azide complex was obtained by replacement of THF through the azide anion in Cp3Sm(THF) (Eq. 6) [74], The molecular structure exhibits different and comparatively large Sm-N-N angles of 134(1) and 151(1)°. The Sm-N bond lengths of 2.47(2) and 2.48(2) A are comparable to those of the inorganic azides. 

Only one crystal structure, that of 2,4-diiodo-3-nitroaniline17, has been retrieved from the CSD. The molecular structure exhibits typical features the diminished A1 angle (116.7°) and the elongated B1 bond (1.410 A). 

In a second design stage, the chemical library was evaluated with in silico health hazard estimation methods developed by lUCT and state of the art eco-tox expert systems. Prediction of the health hazard and eco-toxicological profiles and physico-chemical properties with a sufficient degree of confidence allowed selection of those molecular structures exhibiting lower levels of intrinsic hazard. Figure 10.4 shows the calculated health hazard distribution of the SOLVSAFE dataset.

Clusters composed out of a few atoms are better described and modeled as supra-molecular structures exhibiting no cluster type behavior such as e.g. a well-defined particle plasmon resonance (Figure 3). Ultra-large metal colloids of 300 nm or more exhibit macroscopic behavior such as metallic luster and bulk conductivity (Figure 4). Colloidal structures made up of a plurality of individual clusters are often referred to as mesoscopic systems, cluster matter or nano-crystalline materials. Thus, colloidal particles cover an extreme wide range in size [1,2,3,4].
