By looking at c you can recognize the basis and then you can abstract the space lattice.
Describe this structure as a attice and a basis.
Lattice with a basis consider the following lattice.
In a general case crystal structure can be considered as crystal structure lattice basis.
This generates a structure that is referred to as a crystal a crystalis defined as a latticewith a basisadded to each lattice site.
A basis is a collection of atoms in particular fixed arrangement in space.
Clearly it is not a bravais lattice in a bravais lattice the lattice must look exactly the same when viewed from any lattice point it can be thought of as a bravais lattice with a basis consisting of more than just one atom per lattice point two atoms in this case.
This classification is based on the kind of atoms present in the face within a lattice structure.
It does not matter where the basis is put in relation to a lattice point.
An atom or a group of atoms associated with each lattice point in crystal.
Thus in fig 2 the basis is represented by the two atoms a and a1.
The lattice is defined by fundamental translation vectors.
Conventional or prescriptive construction practices are based as much on experience as on technical analysis and theory.
1 diamond structure fig.
The basis is a set of atoms which is located near each site of a bravais lattice.
Translationally periodic arrangement of atoms in space.
Lets see how a two dimensional lattice may look.
Usually the basis consists of an atom a group of atoms or a molecule.
Crystal lattices can be classified as either monatomic or polyatomic.
If there is only one type of.
Translationally periodic arrangement of points in space.
It is used to describe the structure of a crystal.
