## Abstract The compound __trans__‐1,5‐dichloro‐9,10‐diethynyl‐9,10‐dihydroanthracene‐9,10‐diol (DDDA) has an inversion center as the only molecular symmetry element and yet does not occupy an inversion center in the centrosymmetric space group that it adopts in the crystal structure. The reason fo

The electron impact-induced fragmentations of 23 9,104isubstituted 2,3,6,7-tetraalkoxy-9,10-dihydroanthracenes, including six stereoisomeric pairs, were studied. The loss of the $)-(or 10-jsubstituent constitutes the main fragmentation route. The resulting ions give rise to a remarkable violation of

Flash photolysis of bis [4,5di(methylsulfanyl)1,3-dithiol-2-ylidene]-9,10-dihydroanthracene (1) in chloroform leads to formation of the transient radical cation species 1 . which has a diagnostic broad absorption band at l max % 650 nm. This band decays to half its original intensity over a period o
