摘要: The solid complexes of Cr(III), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) with 2-[5-(2-hydroxy phenyl) 1,3,4-oxadiazol-2yl]-5-methyl-2, 4 dihydro-3 H -pyrazol-3-one] have been synthesized characterized by elemental analysis, molar conductance, magnetic susceptibility, UV-Visible spectroscopy. FT-IR data suggest that the ligand behaves as a neutral bidentate NO donor atoms sequence towards central metal ion. microanalytical reveals stereochemistry has found to be 1:1(metal:ligand) except Ni(II) complex which is formed in1:2 ratio. physicochemical octahedral geometry for all were square planner tetrahedral respectively. (L) its screened their antibacterial activity against E-coli Bascillus microorganisms andfungicidal Aspergillusnigar Candida albicans respect standard antibiotic drugs tetracycline Amphoteriain Keywords: Pyrazol Oxadiazol complexes.
