1,4-Bis(pyridin-3-ylmeth-oxy)benzene.

ABSTRACT: The asymmetric unit of the centrosymmetric title compound, C(18)H(16)N(2)O(2), contains one half-mol-ecule. The central benzene ring forms a dihedral angle of 66.8?(1)° with two outer aromatic rings. In the crystal structure, weak inter-molecular C-H?N hydrogen bonds link mol-ecules into sheets parallel to (104).
