 Title    Elementorganische Verbindungen mit o-Phenylenresten, XXVIII [1] Charge-transfer  
 Abstract    Komplexe von 2,3,7,8-Tetraalkoxy-chalkogenanthrenen mit 7,7,8,8-Tetracyan-2,3?5,6-tetrafluor-chinodimethan Organometalloidal Compounds with o-Phenylene Substituents, Part XXVIII [1] Charge-Transfer Complexes of 2,3,7,8-Tetraalkoxy-chalcogenanthrenes wjth 7.7.8.8-Tetracyano-2,3,5,6-tetrafluoro-quinodimethane -selenanthrene, as well as -tetraethoxythianthrene gi­ ve isostructural 1:1 charge-transfer complexes with 7,7,8,8-tetracyano-2,3,5,6-tetrafluoro-quinodimethane. In the columnar crystal structures there are alternating donor and acceptor molecules. The chalcogenanthrene molecules which are folded at their E -E axes in the pure state, are planar in the complexes indicating a charge-transfer according to [donor]+ [acceptor]-. Consecutive molecules of the stacks are arranged in such a way that an optimum overlap of the HOMO of the donor and the LUMO of the acceptor, both of which are of 7T-type character according to MNDO calculations, is secured.
