| Abstract: | The complexes [Re{MeN(CH2CH2O)(CH2CH2OH)-κ3N,O,O}(CO)3] (1), [Re{N(CH2CH2O)(CH2CH2OH)2-κ3N,O,O}(CO)3] (2), [Me3NH]2[(OC)3Re{N(CH2CO2)2-κ3N,O,O}CH2CH2{N(CH2CO2)2-κ3N,O,O}Re(CO)3] (3), [Me3NH]2[Re2{μ2-2,6-(O2C)2(C5H3N)-κ3N,O,O}2(CO)6] (4) and [Re2{μ2-2,6-(OCH2)(C5H3N)(CH2OH)-κ2N,O}2(CO)6] (5) were synthesized in high yields via the reactions of [Re2(CO)10] and Me3NO with MeN(CH2CH2OH)2, N(CH2CH2OH)3, EDTA, pyridine-2,6-dicarboxylic acid and pyridine-2,6-dimethanol, respectively. Complexes 1-5 were characterized by IR and 1H NMR spectroscopy, elemental analysis and X-ray crystallography. |
