the regular, geometric arrangement of atoms in a solid.

A substance (usually solid but can be liquid) in which the atoms or molecules are arranged in a definate pattern that is repeated regularly in three dimensions. Crystals tend to develop forms bounded by definitely oriented plane surfaces that are harmonious with their internal structure. They may belong to any of six crystal systems: cubic, hexagonal, tetragonal, orthorhombic, monoclinic, or triclinic.

(cryst'-tal-line) Having the properties of a crystal, specifically a regularly repeated long-range three dimensional internal arrangement of atoms.

A crystalline substance.

A certain amount of crystalline fragrance sub stances can be dissolved, without problems, in the, liquid ingredients of a perfume oil. In general they possess good fixative properties. But to( high a percentage of crystalline substances, an( especially low temperatures, can cause what i known as "crystallizing-out"-the appearance o crystals in the liquid.
