# Geometries of different molecules The image shows different molecular geometries. Each row represents a different symmetry, represented by the value of *n*. | n | Base | Molecular shape | |---|---|---| | 2 | Linear | Linear | | 3 | Equilateral triangle | Bent | | 4 | Regular tetrahedron (angles 109.47°) | Pyramidal with a triangular base | Bent | | 5 | Triangular bipyramid (angles 90° and 120°) | Non-regular tetrahedron | T-shaped | Linear | | 6 | Regular octahedron (angles 90°) | Square-based pyramid | Square | Linear | **Notes:** * The diagrams show the arrangement of atoms in a molecule. * The *n* value indicates the symmetry of the molecule. * The labels like *AX2E0*, *AX3E0*, etc. represent specific descriptions of the molecular geometries. * The specific angles are given for some cases, such as the tetrahedral angles.
