What the meaning about body centerde orthorhombic?

A body-centered orthorhombic structure is a type of crystal lattice system characterized by three mutually perpendicular axes of differing lengths. In this arrangement, there is one atom at each corner of the orthorhombic unit cell and one atom at the center of the cell, making it "body-centered." This structure is one of the seven crystal systems and is significant in materials science for understanding the properties of certain metals and alloys. Examples of materials with a body-centered orthorhombic structure include certain forms of phosphorus and certain metal alloys.
