 Title    Poly-trans(alkinyl)phthalocyaninatosihcium(rV) Synthesis and Properties of a New Kind of One-Dimensional Conductors Poly-trans (alkyny 1)phthalocyaninatosilicon (IV)  
 Abstract    Dichloro(phthalocyaninato)silicon(IV) (1) reacts with various bis-bromomagnesium-alkynes to form the corresponding poly-trans(a]kynyl)phthalocyaninatosilicon(IV) com-pounds (5), (11) and (13). The electrical conductivity of 5, 11 and 13 was measured with and without doping.

 Title    X-Ray Investigations of the Low-Temperature Phases of the Organic Metals a-and /KBEDT-TTF)2I3  
 Abstract    The structure of single crystals of the organic metals a-and /?-(BEDT-TTF)2I3* was determined at 100 K, well below the phase transitions indicated by resistivity and thermopower measurements as well as by differential therm al analysis. In the a-phase no unusual change of the room temperature unit cell but a slight variation in the triiodide network and especially a more pronounced dim erization in one of the two donor stacks have been found. The /?-phase develops a superstructure with a unit cell volume three times as large as that at room temperature and with pronounced distortions of the I 3-ions.

 Title    New 7r-Donor Molecules with a Pyrazino Group and their Conducting Salts  
 Abstract    The preparation and characterization of some 7r-donors with a pyrazine-edge-group as well as with tetrathiapentalene-, thiophene-, and dihydrobenzoselenophene-spacer-groups are de­ scribed. Some of these donors give conducting charge transfer complexes with TCNQ and/or cation radical salts with I3-, BF4-and PF6-as counter anions. In tro d u c tio n

ESR spectra and preliminary X-ray dif­ fraction measurements indicate that the salts crystallize in the r-phase (tetragonal system). In troductio n
