Answer:
In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material.[3] 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.
The (3-D) crystal structure of H2O ice Ih (C) consists of bases of H2O ice molecules (C) located on lattice points within the (2-D) hexagonal space lattice (A). The values for the H–O–H angle and O–H distance have come from Physics of Ice[1] with uncertainties of ±1.5° and ±0.005 Å, respectively.
The lengths of the principal axes, or edges, of the unit cell and the angles between them are the lattice constants, also called lattice parameters or cell parameters. The symmetry properties of the crystal are described by the concept of space groups.[3] All possible symmetric arrangements of particles in three-dimensional space may be described by the 230 space groups.
The crystal structure and symmetry play a critical role in determining many physical properties, such as cleavage, electronic band structure, and optical transparency.
