6,6'-[(1E,1'E)-Oxybis(4,1-phenyl-ene)bis-(aza-nylyl-idene)bis-(methanylyl-idene)]bis-(2-methyl-phenol): supra-molecular assemblies in two dimensions mediated by weak C-H?N, C-H?O and C-H?? inter-actions.

ABSTRACT: The title compound, C28H24N2O3, is a flexible Schiff base, having a dihedral angle of 59.53?(5)° between the mean planes of two phenyl rings bounded in the centre by a single O atom. The dihedral angles between the mean planes of the phenyl rings bonded to the central O atom and the mean planes of the terminal methyl-phenol rings are 31.47?(6) and 36.03?(5)°, respectively. The sp2-hybridized character of the azanylylidene groups is confirmed by their bond lengths and bond angles. In the crystal, mol-ecules are linked into centrosymmetric dimers by weak C-H?N inter-actions and connected into dimeric chains through weak C-H?O inter-actions. These chains are inter-connected into a two-dimensional network parallel to (1[Formula: see text]1) via weak C-H?? inter-actions.
