title: 2,2'-Dichloro-1,1'-[(pentane-1,5-diyldi-oxy)bis-(nitrilo-methyl-idyne)]dibenzene.
abstract: The mol-ecule of the title compound, C(19)H(20)Cl(2)N(2)O(2), which lies across a crystallographic inversion centre, adopts a linear configuration. The dihedral angle between the two halves of the mol-ecule is 5.14 (2)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link neighbouring mol-ecules into an infinite zigzag chain supra-molecular structure.
