Abstract

As a result of triple condensation of malonodinitrile with benzaldehyde and ethyl 2-chloro-3-oxobutanoate a compound with 3-azabicyclo[3.1.0]hexane framework is formed whose crystal structure is determined by X-ray crystallography. In the crystal structure a layered character of the molecular packing is found. Molecules are linked in the layer by H bonds of N-H…O=C and C-H…O=C types and also a large number of atom-atom contacts whose energy corresponds to potential wells.
