title: 3,3'',4,4''-Tetra-meth-oxy-1,1':4',1''-terphen-yl.
abstract: The title mol-ecule, C(22)H(22)O(4), is centrosymmetric with an inversion centre located at the centre of the benzene ring. The 3,4-dimeth-oxy-benzene 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 mol-ecules into a two-dimensional polymeric structure lying parallel to (100).
