Amorphous solids which don't have regular periodic arrangement. It may have short range but don't have any long rang order.
Silver - fcc.
Lead - fcc.
Mica - monoclinic.
But glass doesn't have any crystal structure.

Glass is amorphous (SiO2) and Quartz is crystalline.

Amorphous solids on the other hand, do not have a regular and periodic arrangement of atoms. All the bonds are not equally strong. These solids do not have a precise melting point.
Examples of amorphous solids are rubbers, glass, plastic, cement and paraffin.

An amorphous solid is a solid in which there is no long-range order of the positions of the atoms.
