  ABSTRACT: Complexes of chromium(III) metal ion with schiff base i.e. 2,3,9,10 tetraphenyl-1,4,8,11-tetra- azacyclotetradeca-1,3,8,10 tetraene. (BPD) 2,4,10,12-tetramethyl-1,5,9,13-tetraazacyclohexadeca- 1,4,9,12 tetraene. (ADP) 2,3,9,10 tetramethyl 1,4,8,11 tatraazatetredeca-1,3,8,10 tetraene (DDP) have been synthesized and characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, electronic and epr spectral studies. On the basis of elemental analysis the complexes were found to have composition CrLX3 (X = Cl-, , NCS-), Molar conductance, measured in DMF solution of these complexes indicates that the complexes are 1:1 electrolytes in nature, therefore the complexes may be formulated as [CrLX2]X. These complexes show magnetic moment in the range of 3.80 - 3.84 B.M. corresponding to three unpaired electrons. EPR and electronic spectral studies reveal that the complexes possess six-coordinated octahedral geometry. The ligand field parameters were calculated using various energy level diagrams. In vitro synthesized compounds and metal salts have also been tested against some species of plant pathogenic fungi and bacteria in order to assess their antimicrobial properties.
