C₁₂H₁₀ Biphenyl (twisted)

Two rings twisted by 44° · point group D2 · order 4

Open C₁₂H₁₀ in 3D →

Point group
D2 — A C2 principal axis and 2 C2 axes perpendicular to it, with no mirror plane. Molecules in this group are chiral.
Order
4
Operations
E, C₂(z), C₂(y), C₂(x)
Shape
Two rings twisted by 44°
Atoms
22 (C × 12, H × 10)

Symmetry elements of C₁₂H₁₀

  • C₂ (x) — along the bond between the rings
  • C₂ (y) — perpendicular to that bond, through its midpoint
  • C₂ (z) — perpendicular to that bond, through its midpoint

Structure

  • C–C between rings 1.49 Å, ring C–C 1.39 Å
  • Dihedral angle 44° in the gas phase
  • Three C₂ axes and nothing else: a chiral conformation
