CO Carbon monoxide

Linear · point group C∞v · order ∞

Open CO in 3D →

Point group
C∞v — A linear molecule without a centre of inversion: a C∞ axis along the bonds and an infinite number of mirror planes containing it.
Order
∞
Operations
E, 2C∞, ∞σᵥ
Shape
Linear
Atoms
2 (C, O)

Symmetry elements of CO

  • C∞ — the molecular axis: any rotation leaves the molecule unchanged
  • σᵥ (one of ∞) — any plane containing the axis
  • σᵥ (another) — any plane containing the axis

Structure

  • C≡O 1.128 Å
  • A diatomic molecule
  • Lone pair on C and on O
