[DOC] [TLE] Crystal structure - Wikipedia [PAR] 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 .... Some directions and planes are defined 
by symmetry of the crystal system. [DOC] [TLE] Properties of Matter: Solids - Live Science [PAR] Jul 22, 2014 ... In crystalline solids, the atoms, ions or molecules are arranged in an ordered and symmetrical pattern that is repeated over the entire crystal. The smallest repeating structure of a solid is called a unit cell, which is like a brick in a wall. Unit cells combine to form a network called a crystal lattice.
