摘要：

Low-temperature (199 K) X-ray structure analyses of the azaspiropentene 1 and its dimer 2 have been undertaken. The peripheral bonds of 1(C - C 1.544, C = N 1.278 angstrom) are elongated because of steric strain and conjugation with the phenyl ring (for C = N). The distal bond (C - C 1.485 angstrom) in the three-membered ring of 2 is shortened by the substituent effects of the N = C and C = N groups.
