#allotropic

• Allotropic — Relating to simple substances or chemical elements: presenting allotropy; capable of manifesting or crystallizing in two or more distinct external shapes or molecular and crystalline structures, possessing different physical properties, although the raw elemental chemical composition remains identical (for instance, diamond and graphite as allotropic forms of carbon).
• Allotropic — Pertaining to allotropy or characterized by the existence of multiple molecular or crystalline structural forms of the same chemical element; specific to states where the atoms of a simple substance are arranged in different spatial geometries, generating distinct physical properties despite an identical raw elemental composition. This structural type of molecular behavior controls the phase transitions of many industrial materials.
