P-Dimethylaminobenzaldehyde semicarbazone: The bonding abilities of imine nitrogen atom

The crystal and molecular structures of p-dimethylaminobenzaldehyde semicarbazone and p-dimethylaminobenzaldehyde semicarbazone hydrochloride have been determined. On the basis of quantum-mechanical calculations the availability of the imine nitrogen atom for bonding with molecular species was analysed and also the complete assignment of the experimental IR spectrum was performed. The p-dimethylaminobenzaldehyde semicarbazone was characterised by thermogravimetric analysis in conjunction with evolved gases in the air atmosphere.
