Being isomorphous with chromium ( III ) chloride ( CrCl 3 ), it exhibits a cubic-closest packing arrangement in a double-layer crystal lattice.
22.
A preponderance of amino acids with small, nonreactive side groups is characteristic for structural proteins, for which H-bonded close packing is more important than chemical specificity.
23.
And indeed the crystalline simple metal structures are often either close packed face centered cubic ( fcc ) or hexagonal close packing ( hcp ) lattices.
24.
The MG structure is believed to lack the close packing of amino acid side chains that characterize the native state ( "'N "') of a protein.
25.
Despite this close packing of the orbits, dynamical integrations indicate the system has the potential to be stable on a time scale of billions of years.
26.
With other workers he developed LCP theory, ( ligand close packing theory ), which for some molecules allows geometry to be predicted on the basis of ligand-ligand repulsions.
27.
Regular hexagonal close packing of spheres would predict that each atom has 12 nearest neighbours and a triangular orthobicupola ( also called an anticuboctahedron or twinned cuboctahedron ) coordination polyhedron.
28.
In the upper 80 m of the ice sheet, the firn or the snow gradually compacts to a close packing of ice crystals of typical sizes 1 to 5 mm.
29.
The structure of the wulfenite-" I " 4 1 / a system can be described as a close packing of tetrahedral MoO 4 2 " anions and Pb 2 + cations.
30.
When cooled quickly, the chains tightly align, giving PFO a close packing factor, though because of the high complexity of the chains, this sometimes gets messy and creates the amorphous state.
