摘要:
The molecular structure of 7-acetamido-2-methyl-quinoline-5,8-dione has been determined and the reactivity of 7-acetamido-2-methyl-quinoline-5,8-dione (1) and 6-acetamido-2-methyl-quinoline-5,8-dione (2) towards Re(CO)(5)Cl has been examined. Two novel tricarbonyl rhenium complexes, fac-[Re(CO)(3)(7-acetamido-2-methyl-quinoline-5,8-dione) Cl]center dot CHCl(3) (3 center dot CHCl(3)) and fac-[Re(CO)(3)(6-acetamido-2-methyl-quinoline-5,8-dione) Cl](2)center dot CHCl(3)(4 center dot CHCl(3)), have been synthesized and characterized spectroscopically and structurally. The electronic spectrum of 3 was investigated at the TDDFT level employing B3LYP functional in combination with LANL2DZ. (C) 2010 Elsevier B.V. All rights reserved.
