Abstract

Macrocyclic complexes with bivalent metal ions  Co(II), Ni(II), Cu(II) have been synthesized by  [2+2] condensation of 2,6 pyridine di carboxylic  acid and thiourea by template method in  ethanolic medium. The synthesized complexes  have been characterized with the help of various  physico-chemical techniques viz. elemental  analyses, magnetic susceptibility, conductivity  measurements and spectral (IR, UV and EPR)  techniques. The low value of molar conductivity  indicates the non-electrolyte nature of the  complexes. All the complexes are of high-spin  type. On the basis of above studies an octahedral  geometry has been assigned for Co(II) and Ni(II)  complexes whereas tetragonal geometry around  the Cu(II) ion. The biological activities of the  metal complexes have been tested in vitro against  a number of bacterial species to assess their  inhibiting potential. Cu(II) complexes were found  to more active as compared to Co(II) and Ni(II)  complexes.
