4,4′-Dichloro-2,2′-[2,2-dimethyl­propane-1,3-diylbis(nitrilo­methyl­idyne)]diphenol

The crystal of the title Schiff base compound, C(19)H(20)Cl(2)N(2)O(2), contains of two crystallographically independent mol­ecules with similar conformations. In each mol­ecule, two intramolecular O—H⋯N bonds generate S(6) motifs. The N atoms are also in close proximity to two H atoms of the dimethyl­propane groups, with H⋯N distances between 2.59 and 2.62 Å. The imine group is coplanar with the benzene ring. The dihedral angles between the benzene rings in the two independent mol­ecules are 58.20 (12) and 47.95 (12)°. The structure displays short inter­molecular Cl⋯Cl [3.3869 (11) Å] and Cl⋯O [3.175 (2)–3.204 (2) Å] inter­actions. The crystal structure is further stabilized by weak inter­molecular C—H⋯O, C—H⋯π and π–π [centroid–centroid distances 3.6416 (13)–3.8705 (14) Å] inter­actions.
