👉 "Merocrystalline" is a term used in crystallography and crystal chemistry, referring to a type of crystalline structure where all atoms or molecules are arranged in the same plane. This is distinct from "crystallographic", which refers to the arrangement of atoms or molecules in space. In crystallography, merocrystalline crystals are characterized by their three-dimensional (3D) shape and the arrangement of atoms or molecules along a single plane. These structures
