 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,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.

 Title    Struktur von C2C16N4P2, dem R eaktionsprodukt von D icyandiam id mit PC15 Structure of C 2C16N4P2, the Reaction Product of Dicyandiamide with PC15  
 Abstract    The reaction product of dicyanodiamide with PC15 (1:2) is 2,2,4-trichloro-2,2-dihydro-6-trichlorophosphazeno-1.3,5,2A5-triazaphosphorine and not 2.4,6-trichloro-2,2-dihydro-2-trichlorophosphazeno-l,3,5,2A5-triazaphosphorine as reported in the literature. This is con­ firmed by an X-ray structure determination at 90K: Space group P 2,/c, a = 17.258(5), b = 9.664(3), c = 15.070(4) Ä, ß = 114.05(2)°, Z = 8, R = 3.99%. Both molecules of the asymmetric unit show about the same conformation with approximate C s-m -symmetry as was also obtai­ ned by semi-empirical MNDO calculations. The thermal motion analysis establishes that the molecules cannot be described as 'rigid bodies', and that the easy deformability of the exocyclic C-N-P angles allows the 'rigid' NPC13 tetrahedra to perform almost isotropic librations.
