Reactions of chromium, molybdenum and tungsten carbonyls with a tetradentate schiff base
Interaction of metal carbonyls M(CO) 6 (M = Cr, Mo and W) with the tetradentate Schiff base bis(salicylaldehyde)phenylenediimine (salphenH 2 ) was studied in THF. Under reduced pressure, reaction of salphenH 2 with M(CO) 6 (M = Cr, Mo) yielded Cr(CO) 2 (salphen) 1 and MoO(CO)(salphen) 2. The complex...

The UV-vis spectra of the complexes in different solvents showed bands due to either metal-to-ligand or ligand-to-metal charge transfer. Thermal properties of the chromium and molybdenum complexes were investigated by thermogravimetric techniques. |
