STRUCTURE OF 5-NITRO-2-TOSYLAMINOBENZALDEHYDE DI(MORPHOLIN-4-YL)-AMINAL COMPLEX WITH CARBON-TETRACHLORIDE

The 5-nitro-2-tosylaminobenzaldehyde di(morpholin-4-yl)aminal forms a stable complex with carbon tetrachloride in the crystal phase. X-ray s tructural study of this complex indicates an essentially shortened int ermolecular contact of 2.89 Angstrom between the oxygen atom of the ni tro group and one of the chlorine atom of the CCl4 molecule. Quantum-c hemical calculations by semiempirical AMI method showed that the forma tion of such complex did not cause considerable decrease of system ene rgy or change of charge distribution in molecules. It was supposed tha t this associate has van der Waals character.
