摘要：
The two merocyanines 7-(4-dimethylaminophenyl)-2,3,4,4a,5,6,10,10a-octahydroanthracen -2-one [C22H25NO, (2)] and [2,3,4,4a,5,6,10,10a-octahydro-7-(5-piperidino-2-thienyl)- 2-anthrylidene]methanedicarbonitrile [C26H27-N3S, (4)] show somewhat shortened single bonds [1.434(4)-1.452(4) angstroms in (2) and 1.421(4)-1.425(4) angstroms in (4)] and elongated double bonds [1.345(4)-1.358(4) angstroms in (2) and 1.355(4)-1.365(4) angstroms in (4)] compared to standard bond lengths in polyenes. A comparison of the merocyanines reveals that (4) exhibits a slightly smaller bond length alternation within the rigidized hexatriene moiety than (2), probably because of an increased ground-state polarization.
