The complexes have been characterized by the elemental analysis, molar conductance measurement, magnetic susceptibility measurements, IR, electronic and EPR spectral studies. The molar conductance of the complexes in DMSO correspond to nonelectrolytic nature for Mn(II), Co(II), Cu(II). Thus, these complexes may be formulated [M(L)X2] (where M = Mn(II), Co(II), Cu(II) and X=Cl-, NO3 -, OAc-, NCS-). On the basic of IR, electronic and EPR spectral studies an octahedral geometry has been assigned for Mn(II) and Co(II) complexes and distorted octahedral geometry for Cu(II) complexes. In vitro the complexes were against two pathogenic fungi (i.e. Alternaria alternata and Aspergillus niger) to access growth inhibitor potential.</p> https://journalofchemistry.org/paper/561/ Macrocyclic Coordination Chemistry IR UV EPR
