Darstellung und Strukturen von (η6-Diaren)TiII-bis(tetrachloroaluminat)Komplexen, Diaren = Biphenyl oder 3,5,3′,5′-Tetramethyl-biphenyl
摘要:
Syntheses of (eta (6)-diarene)T-II(AlCl4)(2) complexes were performed by the Fischer-Hafner method. The diarenes employed were biphenyl and 3,5,3',5'-tetramethyl-biphenyl. In each of the resulting complexes, (eta (6)-C12H10)Ti-II(AlCl4)(2) (1) and (eta (6)-C16H18)Ti-II(AlCl4)(2) (2), only one C-6-ring of a diarene is coordinatively active. 1: Space group Pbca, Z=8, lattice constants at 20 degreesC: a = 16.864(3), b = 13.931(3), c = 18.807(3) Angstrom; R-1 = 0.048. 2: Space group P2(1)/n, Z= 4, lattice constants at 20 degreesC: a=9.775(1), b=13.720(1), c=20.214(1)Angstrom; beta =95.50(1)degrees; R-1= 0.050.
