3,3′′,4,4′′-Tetra­meth­oxy-1,1′:4′,1′′-terphen­yl

The title mol­ecule, C(22)H(22)O(4), is centrosymmetric with an inversion centre located at the centre of the benzene ring. The 3,4-dimeth­oxy­benzene fragment is essentially planar [maximum deviation = 0.400 (2) Å] and twisted relative to the central benzene ring, forming a dihedral angle of 21.25 ...

Descripción
Sumario:The title mol­ecule, C(22)H(22)O(4), is centrosymmetric with an inversion centre located at the centre of the benzene ring. The 3,4-dimeth­oxy­benzene fragment is essentially planar [maximum deviation = 0.400 (2) Å] and twisted relative to the central benzene ring, forming a dihedral angle of 21.25 (7)°. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional polymeric structure lying parallel to (100).
