3-Methoxy-5-(4-methylphenyldiazenyl)salicylaldehyde and 3-methoxy-5-(2-methylphenyldiazenyl)salicylaldehyde
The two title molecules, both C15H14N2O3, are roughly planar and display a trans conformation with respect to the –N=N– double bond, as found for other diazene derivatives. In both compounds, there are intramolecular O—H…O hydrogen bonds and the crystal packing is governed by weak intermolecular C—H…O hydrogen bonds and – stacking.
