Nettet9. Jahn-Teller Theorem (J-T Distortion) • In 1937, Jahn-Teller put forward a theorem known as Jahn-Teller theorem which can explain why certain six-coordinated complexes undergo distortion to assume distorted octahedral (i.e., tetragonal) geometry. • That principle states that if a system has unequally populated degenerate orbitals, the ... Nettet2. jan. 2016 · The distortion of the square planar geometry resembles the one you predicted: Two opposite oxygens above the plane and two below the plane. This is coherent with a reported ∠ ( O − V − O) = 162 ∘ (diagonally across the square). The authors also reported a large ∠ ( O − V − O) = 103 ∘ and a small ∠ ( O − V − O) = 79 ∘ …

The Jahn-Teller Theorem (named after Hermann Arthur Jahn and Edward Teller), was published in 1937 and essentially means that: "any non-linear molecular system in a degenerate electronic state will be unstable and will undergo distortion to form a system of lower symmetry and lower energy thereby … Nettet27. feb. 2024 · 4 answers.
