8,789 structures were reported in New Journal of Chemistry. These 25 journals account for 704,541 of the 996,193 or 70.7% of the structures in the CSD. These data show that most structures are determined by X-ray diffraction, with less than 1% of structures being determined by neutron diffraction or powder diffraction. The number of error-free ...
Both Jmol and JSmol render an interactive 3D representation of a molecule or other structure that may be used as a teaching tool, [5] or for research, in several fields, e.g. chemistry, biochemistry, materials science, crystallography, [6] symmetry or nanotechnology.
Free open-source: Java 3D applet or standalone program: Ovito: MM XRD EM MD: Free open-source: Python [13] [14] PyMOL: MM XRD SMI EM: Open-source [15] Python [16] [self-published source?] According to the author, almost 1/4 of all published images of 3D protein structures in the scientific literature were made via PyMOL.

The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
A crystallographic database is a database specifically designed to store information about the structure of molecules and crystals.Crystals are solids having, in all three dimensions of space, a regularly repeating arrangement of atoms, ions, or molecules.
A notable molecule editor is a computer program for creating and modifying representations of chemical structures.. Molecule editors can manipulate chemical structure representations in either a simulated two-dimensional space or three-dimensional space, via 2D computer graphics or 3D computer graphics, respectively.
3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
Structural chemistry is a part of chemistry and deals with spatial structures of molecules (in the gaseous, liquid or solid state) and solids (with extended structures that cannot be subdivided into molecules). For structure elucidation [1] a range of different methods is used.
