Simple Cubic Lattice
Explore the Simple Cubic (SC) lattice, also known as Primitive Cubic. This fundamental crystal structure has atoms only at the corners of the cube with a coordination number of 6. Common in Polonium (Po).
Start Visualization →Body-Centered Cubic (BCC)
Body-Centered Cubic (BCC) structure features one atom at the center of the cube and eight corner atoms. Coordination number: 8. Used by alkali metals and transition metals like iron at room temperature.
Start Visualization →Face-Centered Cubic (FCC)
Face-Centered Cubic (FCC) is a close-packed structure with atoms at each corner and the center of all cube faces. Coordination number: 12. Highest packing efficiency (74%) among cubic systems.
Start Visualization →Sodium Chloride (NaCl) - Rock Salt
The classic rock salt structure: two interpenetrating FCC lattices of Na⁺ and Cl⁻ ions. Coordination: 6:6. The most common structure for 1:1 ionic compounds.
Start Visualization →Cesium Chloride (CsCl)
CsCl features a primitive cubic lattice with a two-atom basis (Cs⁺ at center, Cl⁻ at corners or vice versa). Coordination: 8:8. Common when cation and anion sizes are similar.
Start Visualization →Simple Tetragonal Lattice
A cubic lattice stretched or compressed along one axis (c ≠ a). Used in materials like Tin (white tin) and Indium.
Start Visualization →Simple Orthorhombic Lattice
All axes unequal (a ≠ b ≠ c) with 90° angles. Forms a rectangular prism.
Start Visualization →Simple Monoclinic Lattice
One angle ≠ 90° (usually β), like a distorted or sheared box.
Start Visualization →Triclinic Lattice
All axes unequal, all angles ≠ 90°. The least symmetric of the 7 crystal systems.
Start Visualization →Hexagonal Lattice
Features a primitive cell with a 120° angle in the basal plane. Basis for Hexagonal Close-Packed (HCP) metals like Magnesium and Zinc.
Start Visualization →Rhombohedral (Trigonal) Lattice
A primitive lattice where all sides are equal but angles ≠ 90°. Can be viewed as a stretched/skewed cube. Also called Trigonal.
