Mineral crystals are generally categorized into six different classes, depending on the number, length, and angular relationships between their axes. Their shapes or habits, however, are enormously varied. See the link below.

In the crystal lattice are space which are for molecules, atoms and ions

The atoms in a diamond crystal are in an arrangement called "cubic closest packing". As you might guess from the name, this packs the maximum amount of atoms in the minimum possible space, so diamonds are more dense than, say, graphite, which doesn't pack its atoms as closely together.
A crystal is a mineral where all of the atoms are in a row, this is what makes it kind of clear. What determines its shape is the amount of space it has to form in and will usually have triangular pyramidal edges.
A total vacuum is a space that is completely empty of matter. It is not practically possible to achieve a complete vacuum . An approximation to this is a space with pressure much less than atmospheric pressure.
14 Bravais lattices are known and 230 space groups.
When the crystal systems are combined with the various possible lattice centerings, we arrive at the Bravais lattices. They describe the geometric arrangement of the lattice points, and thereby the translational symmetry of the crystal. In three dimensions, there are 14 unique Bravais lattices which are distinct from one another in the translational symmetry they contain. All crystalline materials recognized until now (not including quasicrystals) fit in one of these arrangements. The fourteen three-dimensional lattices, classified by crystal system, are shown to the right. The Bravais lattices are sometimes referred to as space lattices.=The crystal structure consists of the same group of atoms, the basis, positioned around each and every lattice point. This group of atoms therefore repeats indefinitely in three dimensions according to the arrangement of one of the 14 Bravais lattices. The characteristic rotation and mirror symmetries of the group of atoms, or unit cell, is described by its crystallographic point group.=
there are various ways of placing point in space such that all the points have identical suroundings. these are called Bravais lattices after the scientis Bravais(1848). There are 5 Bravais lattices in 2-D and 14 lattices in 3-D. the five 2-D Bravais lattices are as follows:- 1.oblique 2. square 3. Hexagonal 4. Primitive rectangular 5. Lentred rectangular
There are 14 ways of arranging points in space such that the environment look same from each point

A single crystal is a regular and periodic arrangement of particles inside a crystal in three-dimensional space.
There are no green crystals in the space levels

Space lattice is a three-dimensional geometric arrangement of the atoms or molecules or ions composing a crystal. Space lattice is also known as crystal lattice or Bravais lattice.
