WHAT IS MEANT BY VOIDS? IS VOIDS ALSO PRESENT IN ONE DIMENSIONAL PACKING?

In crystal lattice, following are the main voids

Linear void

This type of void is formed when two large atoms (anions) are arranged linearly. A small atom (cation) can occupy this void.

linear void

Trigonal planer void

Void space among three atoms of same size in a plane is known as trigonal planer void

trigonal-planer-void

Tetrahedral planer void

If one atom is placed over three other atoms which are in contact, then space available among four atoms is called tetrahedral void.

tetrahedral-planer-void

Square planer void

Void space available between four atoms in contact is square planer void

square planer void

Octahedral void

It we put four atoms in a plane which are in contact and put one atom above and one below then, void available among six atoms is called octahedral void

octahedral-void

Cubical void

If we put four atoms in one plane which are in contact and put another four atom over it, then space available is cubical void.
