Unit cell
The crystal structure of a material or the arrangement of atoms within a given type of crystal structure can be described in terms of its unit cell. The unit cell is a tiny box containing one or more motifs, a spatial arrangement of atoms. The unit cells stacked in three-dimensional space describe the bulk arrangement of atoms of the crystal. The crystal structure has a three dimensional shape. The unit cell is given by its lattice parameters, the length of the cell edges and the angles between them, while the positions of the atoms inside the unit cell are described by the set of atomic positions ( xi , yi , zi ) measured from a lattice point.

where can i find the crystal i need to know where i can
find the space group structure
of C2-P21. and the crystal
structure of lithium sulfate
monohydrate

There is a database of inorganic crystal structures at http://icsd.ill.fr/icsd/index. html Try that - there are search boxes for either elements or space group structures Hope that helps |

What is the crystal structure I have a science project
involving making your own
crystals, and I've done
everything, but labeled my
Sugar and Epsom Salt crystals
with thier structure. I cannot
find their structure on the
internet, does anybody know
the structure of Sugar and
Epsom Salt?
|
|
|

crystal structure of Sugar is monoclinic hemihedral , and that of epsom salt is monoclinic hydrate In crystallography, the monoclinic crystal system is one of the 7 lattice point groups. A crystal system is described by three vectors. In the monoclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system. They form a rectangular prism with a parallelogram as base. Hence two pairs of vectors are perpendicular, while the third pair make an angle other than 90°. http://en.wikipedia.org/wiki/M onoclinic_crystal_system hope it will help |

How to determine the Crystal In a question I have the
Diffraction angles of a
certain metal and I want to
determine the crystal
structure ..... FCC or Bcc or
HCP ...... do any one has a
Simple method ...... ?

There isn't a simple one. It's pretty complicated. The link below might be able to help you. physics.valpo.edu/courses/p440 / Diffraction_Crystal_Structure. ppt The link isn't posting properly, try stringing them together. |
