 Title    Synthesis and Crystal Structure of a Polymeric Adduct of 2,2'-Dipyridil and Iodine: CioHgN^  
 Abstract    The reaction of 2,2'-dipyridil with iodine (I2; molar ratio 1:3) in CH2C12 solution yields the polymeric complex 2,2'-dipyridil(I2)3. The crystal structure of the compound was determined from single crystal X-ray data (monoclinic, C2/c, a — 3215.0(16), b = 439.9(1), c = 1824.1(9) pm, ß = 130.79(3)°, Z = 4). 2,2'-Dipyridil(I2)3 forms infinite chains of alternating Iß units and bifunctional dipyri-dil molecules.

 Title    Argon-Matrix Isolation of Bis(carbomethoxy)thiirene: Formation of Acyl and Carbalkoxythioketenes  
 Abstract    Photolysis of argon-matrix isolated 4,5-bis(carbomethoxy)-l,2,3-thiadiazole with A = 254 or 265 nm resulted in the almost quantitative formation of bis(carbomethoxy)-thiirene (3g). Photolysis of 3g could only be carried out by long irradiation times at short wavelength A = 210nm and resulted mainly in extensive fragmentation instead of the formation of bis(carbomethoxy)thioketene, confirming earlier predictions that substituents, especially electron-withdrawing ones, should stabilize the thiirene ring. Methylcarboethoxy and methylacetylthioketene were obtained, however, in the argon-matrix photolysis or flow thermolysis of 4-methyl-5-carboethoxy-or 4-carboethoxy-5-methyl-l,2,3-thiadiazole and 4-acetyl-5-methyl-l,2,3-thiadiazole, respectively.
