Volume : III, Issue : I, February - 2013 “SYNTHESIS AND CHARACTERIZATION OF AZIDOBRIDGED CR, MO, W METAL CARBONYL COMPLEXES” AMIT SINGHAL , MANISH KAUSHIK, MUNESH KUMAR, MANOJ AGARWAL Published By : Laxmi Book Publication Abstract : 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).
