摘要：We have synthesized nine polynuclear complexes {M(CO)3[L]}1a-1c, 2a-2c and 3a-3c (1a, M = Cr, L=L1, R = Me, R' = H; 1b, M = Mo, L=L1, R = Me, R' = H; 1c, M = W, L=L1, R = Me, R' = H; 2a, M = Cr, L=L2, R = Me, R' = Me; 2b, M = Mo, L=L2, R = Me, R' = Me; 2c, M = W, L=L2, R = Me, R' = Me; 3a, M = Cr, L=L3, R = Eth, R' = Eth; 3b, M = Mo, L=L3, R = Eth, R' = Eth; 3c, M = W, L=L3, R = Eth, R' = Eth) by photochemical displacement of three CO group from M(CO) by 4-bromo-2-(2- 6 methylaminoethylimino)methyl]phenol [L1], 4-bromo-2-(2-dimethyla minoethy limino)methyl]phenol [L2], 4-bromo-2-(2-diethylaminoethylimino)methyl]phenol [L3]. The synthesized complexes exhibit variable degree of antibacterial activity. The complexes have been characterized by elemental analysis, IR, [1H]-NMR spectroscopy and magnetic studies. The spectroscopic studies suggest a tridentate behavior of the ligand with the metal (0).
