Crystal structure predict (lattice energy, molecular volume correlate)Dunitz, J DDunitz JD. 2003. Are crystal structures predict- able? Chem Comm 2003:545-548.
Such a characterization of the γ-TeO2 structure is supported by the analysis of the Raman spectra using the lattice dynamical model treatment in which the lattice vibrations are considered jointly with the elastic properties. All the longwave frequencies and the elastic constants were thus estimated....
Crystal lattice: a unit cell based on a, b, c vectors and the crystal build-up. A crystal can be characterized both by the unit cell (the carrier of the chemical composition and atomic structure), and by three translation vectors a, b and c; the latter can be used to build the ...
In the structure drawn, all of the particles (yellow) are the same. In this particular case, the lattice points defining the unit cell coincide with the centers of the crystal's particles. This need not always be the case. The Ionic Lattice If a crystal is formed of ions, the compound ...

Crystal Structure (redirected fromCrystalline lattice) Medical Crystal structure The arrangement of atoms, ions, or molecules in a crystal. Crystals are solids having, in all three dimensions of space, a regular repeating internal unit of structure. ...
Crystal structure does not necessarily depend on the arrangement of individual atoms, etc.; it is expressed by the distribution of imaginary points reflecting the periodicity in crystals, which are called the lattice points. As shown in Fig. 3.2, the arrangement of all of the lattice points is...
