Synthesis, spectral and RAHB studies on some arylhydrazones of β-diketones: crystal and molecular structures of 2-(2-(3-pyridyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione and 2-(2-(2-methoxyphenyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione
hydrogen bonding and as a result the NH proton signals and carbonyl carbon signals are shifted to higher frequency region in NMRspectra. Structural implications imposed by the formation of pseudo six-membered ring after hydrogen bonding is well observed in XRD analysis. XRD analysis also evidences the envelop conformation of the dimedone ring in both the cases and resonance assisted hydrogen bonding (RAHB)
