title: 2,2'-Dichloro-1,1'-[(propane-1,3-diyldi-oxy)bis-(nitrilo-methyl-idyne)]dibenzene.
abstract: The title compound, C(17)H(16)Cl(2)N(2)O(2), assumes a V-shape configuration with a dihedral angle between the two halves of the mol-ecule of 79.60 (4)°. The asymmetric unit comprises one half-mol-ecule with a crystallographic twofold rotation axis passing through the central C atom. There are weak inter-molecular π-π stacking inter-actions between neighbouring benzene rings with inter-molecular plane-to-plane distances of 3.277 (6) and 3.465 (5) Å along the a and c axes, respectively. In the crystal structure, weak inter-molecular C-H⋯O bonds link each mol-ecule to four others to form an infinite three-dimensional network.
