    1. Band structure of molecular solids.
      2. A molecular crystal consists of a individual molecules held together by nonbonded interactions [22].
      The fundamental concept that is used in essentially all theories of molecular solids is that there are two quite different types of bonds.

  • What is the atomic basis of crystallography?

    The crystal basis is the arrangement of atoms that is particular to the mineral being considered.
    Each of these basis units is called a unit cell.
    The unit cells are repeated over and over again in three dimensions to make up a macroscopic crystal..

  • What is the crystalline atomic structure?

    Crystalline Structure
    A crystal is: a solid composed of atoms, ions, or molecules arranged in a pattern that is repetitive in three-dimensions.
    Each crystal structure within a specific crystal system is defined by a unit cell.
    A unit cell is the smallest repeatable subsection of the crystal..

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material, and by introducing of unit cell easily define the smallest repeating units of the full symmetry of the crystal structure.
In order to determine a crystal structure, the unit cell parameters of the crystal are determined based on reconstructed 3D diffraction data. The three shortest and mostly repeated vectors in three different directions that connect the diffraction spots in 3D make up the primitive unit cell in reciprocal space.

How accurate is a crystallographic structure?

Two important measures of the accuracy of a crystallographic structure are its resolution, which measures the amount of detail that may be seen in the experimental data, and the R-value, which measures how well the atomic model is supported by the experimental data found in the structure factor file

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter.
