1,4-Bis[(2,2':6',2''-terpyridin-4'-yl)-oxy]butane.
The title compound, C(34)H(28)N(6)O(2), has an inversion centre located at the mid-point of the central C-C bond of the diether bridging unit. The central pyridine rings of the terpyridyl units and the diether chain are co-planar: the maximum deviation from the 18-atom mean plane defined by the bridging unit and the central pyridyl ring is for the pyridyl N atom which sits 0.055 (1) Å above the plane. The dihedral angles between the terminal pyridine rings with this plane are 10.3 (1) and 37.6 (1)°, repectively. In the crystal, weak C-H⋯N inter-actions link the mol-ecules into infinite chains parallel to the a axis.
